“More than ten” armed men on motorbikes stormed three houses in Aden’s Memdara neighborhood on Thursday, residents said.
The owners fled except for one woman who remained in one of the apartments, the sources said, adding that the gunmen shot her dead before driving off.
A security official in Aden told AFP that “we have received a complaint stating that Islamists have killed a woman.” He did not give any further details.
They took advantage of a year-long uprising in Yemen that ousted veteran strongman president Ali Abdullah Saleh, seizing control of large swathes of territory in the country’s southern and eastern provinces.
Despite giving up most of these territories after an all-out army offensive against them that ended in June, many have infiltrated the once bustling port of Aden in an attempt to impose their strict version of Islamic (sharia) law.
Thought to be linked to Al-Qaeda in the Arabian Peninsula, the militants operate mainly by night, harassing young couples seen together and sometimes launching deadly attacks against security forces.
