The Sri Lankan army chief Mahesh Senanayake has alleged that few of the suicide bombers who carried out attacks on Easter Sunday had visited Kashmir, Kerala and Bengaluru in India to possibly be trained in carrying out terrorist activities.

Lieutenant General Mahesh Senanayake said that the exact reason for their visit is not yet known, but it is suspected that the attackers had travelled to India to also establish links with other terrorist organisations. The army chief in an interview with the BBC said the terrorists had travelled to Bangalore, Kashmir and Kerala according to the information they have.

Meanwhile, central intelligence agencies are investigating the case of a car travelling with three passengers which was halted for possessing a sticker bearing the image of Osama Bin Laden. Security has been tightened in south Indian states, owing to the probability of a terror attack in the area. The Kerala DGP said that the state police has been on high alert ever since the Sri Lanka blasts.

On April 29 the National Investigation Agency arrested a Palakkad native, for allegedly planning a suicide bombing in Kerala. The accused, Aboobacker Siddique, confirmed the NIA’s suspicion when he confessed that he intended to carry out a suicide bombing in Kerala.

According to sources, Siddique had been watching videos and listening to speeches of Zahran Hashim, the mastermind behind the Easter attacks in Sri Lanka. On April 28, the NIA had conducted a raid at Siddique's house in Palakkad and Ahamed Arafat's house in Kasaragod.
