The ATS, in a brief note, said the four accused, who were arrested from the airport, were Sri Lankan citizens and terrorists of the Islamic State.
All they have said so far is that their handler was going to inform them about the exact location and time of the target after they collected the weapons," he said.
The Sri Lanka police on Wednesday said a senior deputy inspector general will head a team appointed to investigate four of its citizens arrested in Gujarat when on an alleged mission to carry out terror activities in India at the behest of the banned Islamic State.
The increase in home-grown radicalised Islamic groups and the rise of Islamic State and Al Qaeda in Bangladesh should be a matter of worry for India, which shares a 4,100 km border with its eastern neighbour, says Rajeev Sharma.
