Boko Haram 'killed woman in labour' during attack

Boko Haram fighters killed a woman as she was in labour during what is feared could be the deadliest attack in the militants' six-year insurgency, Amnesty International claimed on Thursday.

The human rights group said one witness to the assault on Baga, on the shores of Lake Chad in northeast Nigeria, told them the woman was shot by indiscriminate fire that also cut down small children.

"Half of the baby boy (was) out and she died like this," the unnamed witness was quoted as saying.
