Al-Qaeda militants attacked Sayoun airport in Wadi Hadhramout, a military barracks and the main post office of a southern Yemeni city on Thursday in a coordinated attack that set off clashes with troops and killed at least 15 people, the government said.
The Defense Ministry said the deadliest attack in Sayoun took place near a military barracks, where a suicide car bomb destroyed large parts of an adjacent date-processing plant, killing at least nine civilians, including two children and a woman.
A security official said that a number of people are believed to have been buried under the rubble and rescue teams are working to retrieve the bodies. The ministry said the bomber was targeting the barracks but was stopped by security forces outside the compound.
At Sayoun airport, officials said militants approached from three different directions, bombed the air traffic control tower and clashed with troops guarding the facility.
An airplane carrying passengers from the capital Sanaa, which was making a transit stop in Sayoun en route to Dubai, was caught in the crossfire, officials said. One of the passengers told The Associated Press over the phone that there was gunfire all around and soldiers on the runway.
The military deployed tanks and heavy weapons, and eventually forced the militants out, security officials said.
While the airport and the military barracks were under attack, militants in pick-up trucks shelled the main post office in the city, setting parts of the building on fire, but were forced to retreat by security guards, the ministry said.
It added that in all the attacks, six soldiers were killed and others were wounded. It did not specify the number of slain militants. The officials spoke on condition of anonymity because they were not authorized to talk to media.
The attacks appeared to be in retaliation for an earlier raid by security forces in the city, where seven suspected al-Qaida militants were arrested, including a local leader.
The government of Yemen launched a major offensive in the spring in an attempt to drive al-Qaida militants from their southern strongholds.
