Nato: Libya air strike went astray
Nato has acknowledged that one of its air strikes in the Libyan capital Tripoli went astray and may have killed civilians.
The military alliance said the errant strike early on Sunday may have been due to "a weapons system failure".
Libyan officials say nine civilians were killed, including two children. Officials took reporters to the building that was hit, where children's toys, teacups and dust-covered mattresses could be seen amid the rubble.
A Nato commander said it "regrets the loss of innocent civilian lives and takes great care in conducting strikes".
