Gunmen kill 5 Yemeni troops guarding LNG plant - official

ADEN (Reuters) - Suspected al Qaeda militants killed four Yemeni soldiers in their sleep early on Sunday in an attack on forces guarding the country's only liquefied natural gas (LNG) export terminal, a local official said.

The assault follows an escalating campaign of drone strikes by the United States over the past two weeks and warnings of militant attacks that prompted Washington to close embassies across the Middle East and evacuate some staff from Yemen.
