Sana’a (Yemen), June 19 (DPA) Armed militants attacked the headquarters of Yemen’s intelligence services in the southern port city of Aden Saturday, killing seven police personnel and injuring four, a police source and witnesses said.

The militants opened fire on guards as they stormed the Political Security agency compound in Tawahi in Aden, according to witnesses.

‘Seven people were killed,’ a police source told DPA, requesting anonymity.

Two woman police officers and a doctor were among the dead, the source said.

The militants are believed to belong to the Al Qaeda terrorist network.

Residents of adjacent houses said the militants had fired rocket-propelled grenades and detonated hand grenades.

The attack appeared to be a bid to free detainees.

The compound houses high-security jail in which suspected members of Al Qaeda and members of the Yemen’s separatist Southern Movement are incarcerated.
