Sri Lankan security officials have warned that the Islamist militants behind Easter Sunday's deadly suicide bombings were planning more attacks imminently, using a van and bombers disguised in military uniforms.
"There could be another wave of attacks," the head of ministerial security division (MSD), a unit of the police, said in a letter to lawmakers and other security sections, seen by Reuters on Monday (Apri 29).
"The relevant information further notes that persons dressed in military uniforms and using a van could be involved in the attacks," the letter said.
It said the militants were targeting five locations for attacks on Sunday or Monday.
