Seven Indian engineers kidnapped in Afghanistan

Karachi, Jun 29: Four heavily-armed militants attacked the busy Pakistan Stock Exchange on Monday morning, killing four security guards and a police sub-inspector before being shot dead in an exchange of fire, media reports said.

The unidentified militants opened indiscriminate fire and lobbed hand grenades at the main gate of the building as they tried to storm it, Geo News reported.

Police said that all the terrorists have been killed while five persons injured in the attack.

Four security guards and a police sub-inspector were also killed in the attack.

"An unfortunate incident took place at the Pakistan Stock Exchange. They made their way from our parking area and opened fire on everyone," said Abid Ali Habib, Director of Pakistan Stock Exchange.

The firing by militants caused panic among the people in the building.

Sindh province Governor Imran Ismail condemned the incident.

"Strongly condemn the attack on PSX aimed at tarnishing our relentless war on terror. Have instructed the IG & security agencies to ensure that the perpetrators are caught alive & their handlers are accorded exemplary punishments. We shall protect Sindh at all costs," he said on Twitter.

Police and rangers have arrived on the spot and surrounded the area.

Washington, Jun 27: Facebook has said that it will flag all "newsworthy" posts from politicians that break its rules, including those from President Donald Trump.

Separately, Facebook's stock dropped more than 8 per cent, erasing roughly USD 50 billion from its market valuation, after the European company behind brands such as Ben & Jerry's and Dove announced it would boycott Facebook ads through the end of the year over the amount of hate speech and divisive rhetoric on its platform.

Later in the day, Coca-Cola also announced it joined the boycott for at least 30 days.

CEO Mark Zuckerberg had previously refused to take action against Trump posts suggesting that mail-in ballots will lead to voter fraud, saying that people deserved to hear unfiltered statements from political leaders.

Twitter, by contrast, slapped a "get the facts" label on them.

Until Friday, Trump's posts with identical wording to those labelled on Twitter remained untouched on Facebook, sparking criticism from Trump's opponents as well as current and former Facebook employees.

Now, Facebook is all but certain to face off with the president the next time he posts something the company deems to be violating its rules.

"The policies we're implementing today are designed to address the reality of the challenges our country is facing and how they're showing up across our community," Zuckerberg wrote on his Facebook page announcing the changes.

Zuckerberg said the social network is taking additional steps to counter election-related misinformation.

In particular, the social network will begin adding new labels to all posts about voting that will direct users to authoritative information from state and local election officials.

Facebook is also banning false claims intended to discourage voting, such as stories about federal agents checking legal status at polling places.

The company also said it is increasing its enforcement capacity to remove false claims about local polling conditions in the 72 hours before the US election.

Ethan Zuckerman, director of the Massachusetts Institute of Technology's Center for Civic Media, said the changes are a "reminder of how powerful Facebook may be in terms of spreading disinformation during the upcoming election".

He said the voting labels will depend on how good Facebook's artificial intelligence is at identifying posts to label.

"If every post that mentions voting links, people will start ignoring those links. If they're targeted to posts that say things like 'Police will be checking warrants and unpaid traffic tickets at polls' a classic voter suppression disinfo tactic and clearly mark posts as disinfo, they might be useful," he said.

But Zuckerman noted that Facebook "has a history of trying hard not to alienate right-leaning users, and given how tightly President Trump has aligned himself with voter-suppressing misinfo, it seems likely that Facebook will err on the side of non-intrusive and ignorable labels, which would minimize impact of the campaign."

Earlier in the day, shares of Facebook and Twitter dropped sharply after consumer-product maker Unilever announced a new ad boycott on Facebook, Twitter and Instagram through at least the end of the year.

The European company said it took the move to protest the amount of hate speech online.

Unilever said the polarised atmosphere in the United States ahead of November's presidential election placed responsibility on brands to act.

In addition to the decline in Facebook shares, Twitter ended the day more than 7 per cent lower.

Unilever, which is based in the Netherlands and Britain, joins a raft of other advertisers pulling back from online platforms.

Facebook in particular has been the target of an escalating movement to withhold advertising dollars to pressure it to do more to prevent racist and violent content from being shared on its platform.

"We have decided that starting now through at least the end of the year, we will not run brand advertising in social media newsfeed platforms Facebook, Instagram and Twitter in the U.S.," Unilever said.

"Continuing to advertise on these platforms at this time would not add value to people and society."

Facebook did not immediately respond to a request for comment. On Thursday, Verizon joined others in the Facebook boycott.

Unilever "has enough influence to persuade other brand advertisers to follow its lead," said eMarketer analyst Nicole Perrin.

She noted that Unilever pulled back spending "for longer, on more platforms (including Twitter) and for more expansive reasons" in particular, by citing problems with "divisiveness" as well as hate speech.

Sarah Personette, vice president of global client solutions at Twitter, said the company's "mission is to serve the public conversation and ensure Twitter is a place where people can make human connections, seek and receive authentic and credible information, and express themselves freely and safely."

She added that Twitter is "respectful of our partners' decisions and will continue to work and communicate closely with them during this time."

Beijing, Feb 24: The lockdown of Guo Jing's neighbourhood in Wuhan -- the city at the heart of China's new coronavirus epidemic -- came suddenly and without warning.

Unable to go out, the 29-year-old is now sealed inside her compound where she has to depend on online group-buying services to get food.

"Living for at least another month isn't an issue," Guo told news agency, explaining that she had her own stash of pickled vegetables and salted eggs.

But what scares her most is the lack of control -- first, the entire city was sealed off, and then residents were limited to exiting their compound once every three days.

Now even that has been taken away.

Guo is among some 11 million residents in Wuhan, a city in central Hubei province that has been under effective quarantine since January 23 as Chinese authorities race to contain the epidemic.

Since then, its people have faced a number of tightening controls over daily life as the death toll from the virus swelled to over 2,500 in China alone.

But the new rules this month barring residents from leaving their neighbourhoods are the most restrictive yet -- and for some, threaten their livelihoods.

"I still don't know where to buy things once we've finished eating what we have at home," said Pan Hongsheng, who lives with his wife and two children.

Some neighbourhoods have organised group-buying services, where supermarkets deliver orders in bulk.

But in Pan's community, "no one cares".

"The three-year-old doesn't even have any milk powder left," Pan told news agency, adding that he has been unable to send medicine to his in-laws -- both in their eighties -- as they live in a different area.

"I feel like a refugee."

The "closed management of neighbourhoods is bound to bring some inconvenience to the lives of the people", Qian Yuankun, vice secretary of Hubei's Communist Party committee, said at a press briefing last week.

Authorities on Monday allowed healthy non-residents of the city to leave if they never had contact with patients, but restrictions remained on those who live in Wuhan.

Demand for group-buying food delivery services has rocketed with the new restrictions, with supermarkets and neighbourhood committees scrambling to fill orders.

Most group-buying services operate through Chinese messaging app WeChat, which has ad-hoc chat groups for meat, vegetables, milk -- even "hot dry noodles", a famous Wuhan dish.

More sophisticated shops and compounds have their own mini-app inside WeChat, where residents can choose packages priced by weight before orders are sent in bulk to grocery stores.

In Guo's neighbourhood, for instance, a 6.5-kilogramme (14.3-pound) set of five vegetables, including potatoes and baby cabbage, costs 50 yuan ($7.11).

"You have no way to choose what you like to eat," Guo said. "You cannot have personal preferences anymore."

The group-buying model is also more difficult for smaller communities to adopt, as supermarkets have minimum order requirements for delivery.

"To be honest, there's nothing we can do," said Yang Nan, manager of Lao Cun Zhang supermarket, which requires a minimum of 30 orders.

"We only have four cars," she said, explaining that the store did not have the staff to handle smaller orders.

Another supermarket told AFP it capped its daily delivery load to 1,000 orders per day.

"Hiring staff is difficult," said Wang Xiuwen, who works at the store's logistics division, adding that they are wary about hiring too many outsiders for fear of infection.

Closing off communities has split the city into silos, with different neighbourhoods rolling out controls of varying intensity.

In some compounds, residents have easier access to food -- albeit a smaller selection than normal -- and one woman said her family pays delivery drivers to run grocery errands.

Her compound has not been sealed off either, the 24-year-old told AFP under condition of anonymity, though they are limited to one person leaving at a time.

Some districts have implemented their own rules, such as prohibiting supermarkets from selling to individuals, forcing neighbourhoods to buy in bulk or not at all.

"In the neighbourhood where I live, the reality is really terrible," said David Dai, who is based on the outskirts of Wuhan.

Though his apartment complex has organised group-buying, Dai said residents were unhappy with price and quality.

"A lot of tomatoes, a lot of onions -- they were already rotten," he told , estimating over a third of the food had to be thrown away.

His family must "totally depend" on themselves, added the 49-year-old, who has resorted to saving and drying turnip skins to add nutrients to future meals.

The uncertainty of not knowing when the controls will be lifted is also frustrating, said Ma Chen, a man in his 30s who lives alone.

"I have no way of knowing how much (food) I should buy."
