A coalition air strike in Libya has killed seven civilians, according to the BBC.

The report, which quotes a doctor, said the coalition attack on a convoy of Gaddafi loyalists took place on Wednesday in a village 9 miles from Brega.

Brega is one of the frontlines in the battle for Libya where anti-Gaddafi forces are fighting for survival. The control of the oil town is key to the rebels' hopes to mount sustained challenge to the official military.

The coalition forces had targeted a convoy carrying ammunition, but the attack led to the destruction of two nearby homes, causing civilian deaths, the report said. As many as 25 people are reportedly injured in the attack.

The BBC source said the dead were between the ages of 12 and 20. BBC said it hasn’t independently verified the report.
