"All explosives possessed by the terrorist group has been seized. Almost everyone identified with the group have been arrested. Two of their bomb experts have died in the clashes. The police can happily announce that everyone with direct links have been either arrested or killed by now," Wickremaratne said.
Meanwhile, Sri Lanka has issued a Presidential decree banning all forms of face covers including Islamic garments such as burqa.
The ISIS claimed the attacks, but the government has blamed local Islamist extremist group NTJ for the attacks.
Sri Lanka's police chief had reportedly issued a warning on April 11, saying that a 'foreign intelligence agency' had reported NTJ was planning attacks on churches and the Indian High Commission.
