An aid worker says gunmen have kidnapped two foreign aid workers in Somalia.

He says the Medecins Sans Frontieres (Doctors Without Borders) workers were seized in central Somalia on Sunday by around 25 gunmen traveling in two trucks.

The Somali staff traveling with the two hostages were released. One of the captives is European and the nationality of the other is not known.

The aid worker spoke on condition of anonymity because he was not authorized to talk to the media.

Attacks on aid workers are common in Somalia. The government accuses them of helping insurgents and the insurgents accuse them of being spies. Dozens have been killed, kidnapped or threatened within the past year.

Nearly half the population is dependent on foreign aid.
