The deportations come as part of the island nation’s endeavor to restructure its security apparatus as promised by President Maithripala Sirisena following serial terror attacks that rocked Sri Lanka on 21 April, leaving 253 killed and over 500 injured.

Axar.az reports foreign media that the Sri Lankan government has cracked down on terror suspects after the Easter Sunday serial terrorist blasts and deported some 600 foreigners from Colombo last week, including 100 Indians, the Indian daily The Pioneer reported.

There were 200 Muslim religious preachers (Maulvis) among the ones deported, the media report said.

The Sri Lankan government is screening 1,200 individuals suspected to have terror links. After confirmation, they would also be deported from the country.

Clerics from Pakistan and the Maldives were also among those deported from the country.

Apart from the 200 Muslim religious preachers, the island nation's authorities have earmarked 400 others who travelled to the nation on tourist visas and were engaging in radicalization activities.

According to the report, prior to the Easter Sunday attacks, the chief of National Thowheed Jamat, Zaharan Hashim, was in southern India for three months. He was there below the radar of India's Intelligence Bureau and hence remained undetected during his stay in India
