A Kenyan military official says that allied African troops have taken full control of Somalia's Kismayo port, the last stronghold of the Islamist extremist rebels who are fighting against the country's internationally backed government.

Maj. Emmanuel Chirchir, a spokesman for the Kenyan Defence Forces, said through Twitter Tuesday that the Somalia National Army and Kenyan troops had secured Kismayo's central police station and the new airport. He says once the airport is safe military aircraft will start landing there.

Chirchir says bomb experts detonated explosive devises planted at the airport by the al-Shabab rebels, who are allied to Al Qaeda. Allied African troops from the African Union are helping Somalia's fragile government to restore order in the country that has been in chaos since warlords overthrew a longtime dictator in 1991.
