Bomber hits field hospital as Libyan forces battle Islamic State in Sirte

TRIPOLI (Reuters) - A suicide bomber killed three people at a field hospital for forces fighting Islamic State in their Libyan coastal stronghold of Sirte on Sunday, a security source said, and medical staff appealed for help in treating the wounded.

The bomber also wounded seven others and caused extensive damage to the hospital, about 50 km (30 miles) from the front line, the source said. Two other attempted suicide bombings just outside the centre of Sirte did not cause casualties, he said.
