Sana'a: Yemeni security officials say gunmen have attacked a military vehicle, killing all four soldiers inside it.
The officials said the attackers surprised the soldiers with heavy gunfire yesterday night while patrolling a street in Houta, a town in the southern Lahj province.
The gunmen then set fire to the vehicle, the officials said. They spoke on condition of anonymity because they were not authorised to brief the media.
The identity of the gunmen was not immediately known, but the province has seen increased activity by al Qaeda militants and Shi'ite Houthi rebels, both of which oppose the government.
The Houthis swept into Sana'a in September and kept President Abed Rabbo Mansour Hadi under house arrest. He fled to the southern city of Aden last week.
