In Yemen, gunmen have opened fire on a helicopter owned by an American oil company.
Yemeni officials said one bullet hit the aircraft but it landed safely with only one person slightly hurt.
The incident happened shortly after the helicopter left the airport in the capital, Sanaa, to fly to an oil-producing area to the east. The identity of the gunmen is not known.
Yemen was the scene of a bomb attack that killed 17 sailors on an American warship two years ago.
