A powerful blast ripped through a bus carrying Yemeni air force personnel to their Sanaa base Sunday, killing one person and wounding 25, an air force spokesman said.
A bomb planted on the bus exploded while the vehicle was travelling on the road leading to Sanaa international airport, which is adjacent to the base, Colonel Mehdi al-Aydarus told AFP.
A security official had earlier put the death toll at six.

Aydarus said five of the injured were in critical condition.
The director of the nearby Saudi-German Hospital, Abdullah al-Daeri, confirmed the toll.
"This terrorist act aims to destabilise the country and jeopardising the (ongoing) national dialogue," aimed to draft a new constitution and prepare for elections next year, Aydarus said.
The Yemen-based Al-Qaeda in the Arabian Peninsula (AQAP), the most active franchise of the global jihadist network, has been behind numerous attacks on the country's security forces.
