Sheikh Hasina on her way to London

Bangladesh Prime Minister Sheikh Hasina, who resigned on Monday following unprecedented anti-government protests, is on her way to London through India, multiple diplomatic sources said.

Hasina is learnt to be travelling in a transport aircraft of the Bangladesh Air Force and it is expected to have a stopover in India.

It is not immediately clear whether the military transport aircraft will take her beyond India or she will travel to London in a different plane.

India decided to provide a safe passage through the Indian airspace to Hasina's aircraft following a request from Dhaka, the sources cited above told PTI.

Indian government sources said New Delhi is closely following the fast-paced developments in Dhaka.

There is no reaction yet from India on the unfolding developments in Bangladesh.

In Dhaka, Bangladesh Army Chief General Waqar-uz-Zaman said Hasina has resigned and an interim government is taking over the responsibilities.

"I'm taking all responsibility (of the country). Please cooperate," he said in a televised address.

The Army chief said he had met political leaders and told them the Army would take over responsibility for law and order.

More than 100 people have been killed in the protests against the Hasina government over the last two days.

The students' protests in Bangladesh started last month against a controversial job quota scheme. The protests now have turned into an anti-government agitation.

The controversial quota system provided for 30 per cent reservations in civil services jobs for the families of veterans who fought the 1971 liberation war.
