COLOMBO - Sri Lanka's military captured two camps used by the Tamil Tigers' suicide squad, killing 12 rebels and seizing a large number of weapons, officials said yesterday amid concern for civilians trapped in the war zone.

According to the Red Cross, some 250,000 noncombatants are stuck in the 115-square mile area near the town of Mullaittivu where advancing government troops have boxed in the separatist Tamil rebels.
