New Delhi, Apr 23: Delhi Police has booked Jamia students Meeran Haider and Safoora Zargar under the Unlawful Activities (Prevention) Act (UAPA) in a case related to communal violence in northeast Delhi over the Citizenship (Amendment) Act, said a lawyer.

Haider and Zargar, arrested for allegedly hatching a conspiracy to incite the communal riots in February, are in judicial custody. While Zargar is the media coordinator of Jamia Coordination Committee, Haider is a member of the committee.

The police has also booked Jawaharlal Nehru University student leader Umar Khalid under the UAPA in the case, said advocate Akram Khan who is representing Haider in the case.

Haider (35) is a PhD student and the president of RJD youth wing's Delhi unit, while Zargar is an MPhil student of Jamia Millia Islamia (JMI) university.

In the FIR, the police has claimed that the communal violence was a "premeditated conspiracy" which was allegedly hatched by Khalid and two others.

The students have also been booked for the offences of sedition, murder, attempt to murder, promoting enmity between different groups on grounds of religion and rioting.

Khalid had allegedly given provocative speeches at two different places and appealed to the citizens to come out on streets and block the roads during the visit of US President Donald Trump to spread propaganda at international level about how minorities in India are being , the FIR alleged.

In this conspiracy, firearms, petrol bombs, acid bottles and stones were collected at numerous homes, the FIR claimed.

Co-accused Danish was given the responsibility to gather people from two different places to take part in the riots, the police alleged.

Women and children were made to block the roads under the Jafrabad metro station on February 23 to create tension amidst the neighbourhood people, it said.

Over 20 film personalities, including Anurag Kashyap, Vishal Bhardwaj, Mahesh Bhatt and Ratna Pathak Shah, on Sunday had released a statement raising their voice against the arrest of the students and activists by Delhi Police for protesting against the Citizenship (Amendment) Act and demanded their release.

Following this, the police had said investigations into the JMI violence and northeast Delhi riot cases were done impartially, and arrests were made after analysis of forensic evidence.

In December last year, the police had allegedly entered the JMI campus after protests over the CAA, being held a few metres away from the varsity, turned violent.

Rajya Sabha MP and RJD leader Manoj Jha had tweeted, "Delhi Police called him for investigation and then received orders from above and arrested Meeran Haider, who has been helping people during the time of coronavirus outbreak."

The Jamia Coordination Committee (JCC), a group comprising students and alumni from the varsity, had condemned the arrest and demanded his immediate release.

"The country is facing a massive health crisis, however, the state machinery is busy harassing and framing student activists in false cases to suppress voices of dissent," they said.

The JCC said Haider was diligently working to provide ration to the needy during the lockdown. Communal clashes had broken out in northeast Delhi on February 24 after violence between citizenship law supporters and protesters spiralled out of control leaving at least 53 people dead and around 200 injured.

New Delhi, Feb 12: Delhi Chief Minister-designate Arvind Kejriwal was on Wednesday elected as the leader of AAP legislative party, a day after he led the party to an emphatic victory in the Delhi Assembly elections.

Kejriwal was elected as the AAP legislative party leader during a meeting called by him with the newly-elected party MLAs. The meeting was held at the AAP chief's residence.

Atishi, AAP's winning candidate from Kalkaji constituency said after the meeting, "It is definitely a validation of the work that has been done by AAP in the last five years, be it education, health care, water or electricity."

Kejriwal is slated to take oath as the Delhi Chief Minister for the third time at Ramlila Maidan on February 16.

AAP galloped to a landslide victory by winning 62 of the 70 seats in the Delhi Assembly elections in the face of a high-voltage campaign by the BJP, which fielded a battery of Union Ministers and Chief Ministers in its electioneering, spearheaded by Home Minister Amit Shah.

The BJP marginally improved its tally, managing just eight seats from its 2015's tally of three seats. The Congress, which drew a blank in the previous elections, failed to open its account yet again.

Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.
