Aden: A suspected al-Qaeda attack on an army checkpoint in southeast Yemen on Saturday killed one soldier and wounded another, a security source said. The attack targeted an army checkpoint in the Al-Qatn area of the semi-desert Hadramawt province, the source said. The source said that the gunmen, suspected Al-Qaeda militants, had fled. Yemeni troops launched an offensive in late April to dislodge Al-Qaeda militants from their strongholds in the south of the country. One hundred soldiers and 500 militants were killed in the operation, a military spokesman said on Thursday. Al-Qaeda in the Arabian Peninsula is considered by Washington the global jihadist network`s deadliest franchise. The group was created in a merger between the network`s Yemeni and Saudi branches, and it has been targeted by US drone strikes this year. Taking advantage of a collapse of central authority during a 2011 uprising that forced veteran strongman Ali Abdullah Saleh from power, Al-Qaeda seized swathes of the south and east. They remain deeply entrenched in Hadramawt province further east, where they have carried out a series of spectacular attacks in past months.
