A time bomb exploded Thursday outside the newspaper office of a Tamil political party opposed to the Tamil Tiger rebels, injuring two people, police and the defense ministry said.
The van's driver and an aide to EPDP leader Douglas Devananda were injured, police and military spokesmen said.
Police declined to speculate on who carried out the attack. Military spokesman Brig Nalin Witharanage said bomb experts were at the scene. "It is too early to put a blame, but our investigators are on the job," he said.
The EPDP, a coalition partner in the government, has in the past been targeted by Tamil Tiger rebels, their bitter rivals, reports the AP. I.L.
