Indonesia's U.S.-funded police anti-terror squad has killed seven suspected militants over the last three days, but the raids are triggering renewed allegations that the force is failing to try and take suspects alive.

Police spokesman Brig. Gen. Boy Rafli Amar said Sunday that no shots were fired against officers during the raids Friday and Saturday in eastern Indonesia, but that the suspects in at least one of the locations had explosives "ready" to be detonated.

Haris Azhar, chairman of the Commission for Missing Persons and Victims of Violence, says it appeared the suspected militants were victims of "extrajudicial killings" and called for an independent investigation. He says animosity toward the anti-terror squad is driving militancy.

The squad was established with U.S. and Australian help following the 2002 Bali bombings.
