An anti-narcotics helicopter searching for gunmen protecting drug plantations crashed into a mountain in southern Mexico on Wednesday, killing all nine soldiers and two federal pilots onboard, authorities said.
What caused the crash was unclear, but the aircraft may have been attacked by drug smugglers on the ground, according to a statement released by the federal attorney general's office.
Trouble began in the isolated mountains near the town of Tlapa, about 210km southeast of Mexico City, shortly before noon, when a Bell 206 L-IV chopper carrying soldiers and investigators on a routine mission was hit by gunfire from the ground.
