Hawzah News Agency - (Kerala - India) - India has become increasingly vulnerable to the threat of ISIS -inspired terrorist attacks, according to NDTV, citing three intelligence letters sent to police chiefs in the state of Kerala.

“After loss of territory in Iraq and Syria, IS is urging operatives to take up violent forms of jihad while staying back in their respective countries,” read one of the letters.

The terrorist group may also target key installations in Kochi, Kerala’s most populous city with 2 million people, another letter said. Local police officials estimate that roughly 100 Kerala residents have joined IS in the past few years, while around 3,000 have been “deradicalized” and are now under surveillance.
