Yemeni officials say at least three people have been killed in attacks on security and intelligence buildings in the country's southern Abyan province.
Local authorities said Wednesday gunmen on motorcycles using mortars and rocket-propelled grenades opened fire on people inside the two buildings in the provincal capital, Zinjibar.
After the assault and subsequent clashes with police and guards, the attackers fled.
Officials said al-Qaida is believed to be responsible for the attacks, and security had arrested seven suspected insurgents. The militant group was blamed for an attack last month on security headquarters in southern Yemen that left 11 people dead.
