Al-Qaida has claimed responsibility for attacks earlier this month on security and intelligence buildings in Yemen's south that left at least three people dead.
The militant group's regional wing, known as Al Qaida in the Arabian Peninsula, said in an Internet statement Friday the attacks were in retaliation for the killing of at least one militant fighter in Yemen's southern Abyan province.
On July 14, gunmen on motorcycles using mortars and rocket-propelled grenades opened fire on people inside the two buildings in the provincial capital, Zinjibar.
After the assault and subsequent clashes with police and guards, the attackers fled.
Al-Qaida was also blamed for an attack last month on security headquarters in southern Yemen that left 11 people dead.
