Police forces in the Indian cities of Delhi, Mumbai, Bengaluru, Kolkata and Hyderabad have been put on high alert after intelligence agencies reported threat of al Qaeda terror attacks. 

According to intelligence inputs, al Qaeda may target public places, tourist spots, iconic buildings, and places of worship in these cities, said reports on Monday. 

The high alert in major Indian cities comes days after a similar alert following the Paris terror attacks on 13 November. 

Last year, al Qaeda leader Ayman al Zawahiri had announced the formation of an "Indian wing" of the terror group "to raise the flag of jihad" across the subcontinent.
