Security beefed up at airports across country after suspicious bag found at Mangaluru airport

Bengaluru, May 20: A mysterious "boom" heard in large parts of Bengaluru this afternoon left residents of the city and social media users puzzled. While the source of the sound is being investigated, the Indian Air Force (IAF) indicated that it could be the result of "routine test flights that necessitate going supersonic a times".

The sound was heard from as far as the Bengaluru airport in Devanahalli to the IT hub of Electronic City 54 km away. It was also heard in Kalyan Nagar in east Bengaluru, central Bengaluru's MG Road and areas such as Marathahalli, Whitefield, Sarjapur and Hebbagodi.

IAF said no aircraft of training command was flying in the area. "However, ASTE (Aircraft and Systems Testing Establishment) and HAL (Hindustan Aeronautics Limited) could have been undertaking their routine test flying, which necessitates going supersonic at times. These are done well beyond the city limits in specified sectors. However, considering the atmospheric conditions and reduced noise levels in the city during these times, the aircraft sound may become clearly audible even if it happened way out from the city," said the air force statement.

Many people had speculated that the sound could have been caused by a fighter jet such as a Mirage 2000.

"We have also asked the Air Force Control Room to check if it was a jet or supersonic sound. Bengaluru police are awaiting confirmation from the Air Force," Bengaluru police commissioner Bhaskar Rao said in a statement.

It was not an earthquake, Karnataka's state disaster monitoring centre had tweeted earlier.

"Earthquake activity will not be restricted to one area and will be widespread. We have checked our sensors and there is no earthquake activity recorded today," the Karnataka State Natural Disaster Monitoring Centre said, quoting its director Srinivas Reddy.

"The activity reported in Bengaluru is not due to an earthquake. The seismometers did not capture any ground vibration as generally happens during a mild Tremor. The activity is purely a loud unknown noise," the agency tweeted.

#Bangalore and #BangaloreBoom was among the top trends on Twitter this afternoon.

"We are trying to ascertain the source of the noise," a senior police officer said. "In Whitefield area, we have searched on the ground and so far, there is no damage to any property," he added. There were no calls to the police control room reporting any damage.

Bengaluru, Mar 13: Karnataka Health Department is planning to set up a separate hospital for COVID-19 so that the affected can be kept in quarantine at one place.

Presently, it is in the process of setting up separate isolation wards for COVID-19 cases at eight Bengaluru hospitals.

Minister for Medical Education K Sudhakar said on Friday that he has already discussed the idea of a separate facility for COVID-19 cases, so that those isolated, can be kept at a single location to contain the spread of the virus.

New Delhi, Jan 14: The Kerala government has challenged the new Citizenship (Amendment) Act (CAA) before the Supreme Court, becoming the first state to do so amid nationwide protests against the religion-based citizenship law. The Supreme Court is already hearing over 60 petitions against the law.

Kerala's Left-led government in its petition calls the CAA a violation of several articles of the constitution including the right to equality and says the law goes against the basic principle of secularism in the constitution.

The Kerala government has also challenged the validity of changes made in 2015 to the Passport law and the Foreigners (Amendment) Order, regularising the stay of non-Muslim migrants from Pakistan, Bangladesh and Afghanistan who had entered India before 2015.

The Citizenship Amendment Act (CAA), eases the path for non-Muslims in the neighbouring Muslim-majority nations of Pakistan, Afghanistan and Bangladesh to become Indian citizens. Critics fear that the CAA, along with a proposed National Register of Citizens (NRC), will discriminate against Muslims.

The Kerala petition says the CAA violates Articles 14, 21 and 25 of the constitution.

While Article 14 is about the right to equality, Article 21 says "no person will be deprived of life or personal liberty except according to a procedure established by law". Under Article 25, "all persons are equally entitled to freedom of conscience."

Several non-BJP governments have refused to carry out the NRC in an attempt to stave off the enforcement of the citizenship law.

Over 60 writ petitions have been filed in Supreme Court so far against the Citizenship (Amendment) Act. Various political parties, NGOs and also MPs have challenged the law.

The Supreme Court will hear the petitions on January 22.

During the last hearing, petitioners didn't ask that the law be put on hold as the CAA was not in force. The Act has, however, come into force from January 10 through a home ministry notification.
