Trivandrum, May 26: Kerala Coastal Police have been placed on alert after intelligence inputs about ISIS affiliates setting off towards Lakshadweep and Minicoy Island from Sri Lanka, police sources said on Sunday. According to highly-placed sources aware of the matter, as many as 15 ISIS affiliates have set-off in a white boat from Sri Lanka towards Indian islands of Lakshadweep and Minicoy.

Coastal patrolling has been intensified and information has been passed to all Station House Officers (SHO) in the area. The Indian Coast Guard has deployed its ships and maritime surveillance aircraft around the two islands and maritime borders with Sri Lanka in order to thwart any attempt by the ISIS to enter Indian waters.

On April 21, bombings took place at various locations across Sri Lanka in which at least 250 people lost their lives while over 500 were injured in the terror attack. Local terror group NTJ (National Thowheeth Jama'ath), which is an ISIS-affiliate, claimed responsibility for the attack.

Sri Lankan President Maithripala Sirisena on Wednesday extended by a month the state of emergency imposed in the wake of the deadly blasts, citing "public security".The emergency law gives police and the military extensive powers to arrest, detain and interrogate suspects without court orders.
