Fotokol, Cameroon--Chadian combat helicopters struck Boko Haram positions in the Nigerian border town of Gamboru for a second straight day on Sunday, an AFP journalist in a neighbouring town said.
Two military choppers pounded targets in Gamboru for about two hours, setting off loud explosions and sending thick clouds of smoke into the sky, the journalist said from the town of Fotokol about 500 metres (yards) away
