Ethiopian warplanes have struck Somalia's two main airports as part of an intensifying offensive against the Somali Islamist movement.
The fighter jets hit airports in the Somali capital, Mogadishu and the town of Baledogle to the west.
Islamist officials say the attacks injured one woman.
Meanwhile, the Somali government, which Ethiopia is supporting, closed the country's airports and port and urged neighboring countries to prevent people from crossing the border.
In another development, Islamist fighters withdrew from the central town of Beledweyne after two days of Ethiopian airstrikes. Islamist officials described the move as a "tactical retreat."
The fighting in Somalia broke out last Tuesday, after months of rising tension as the Islamists took over much of the country's center and south.
Ethiopia sent forces into Somalia after the Islamists declared a holy war against the nation.
Somalia has not had an effective central government since 1991, when warlords overthrew dictator Mohamed Siad Barre.
Islamist and Ethiopian officials say the past week's fighting has killed hundreds of people. But the death toll has not been independently confirmed.
