MOGADISHU (AFP) - Gunmen abducted two foreign aid workers Tuesday in central Somalia, a security official said, the latest in a string of abductions by militia groups from the war-torn nation. We have reports that two foreign aid workers from DDG (Danish Demining Group) were kidnapped from near the airport at Galkayo by gunmen. We are following up to get further details, said Ali Mohamed, a Somali security official. The foreigners nationalities were not immediately clear, but they are believed to be a man and a woman. DDG clears landmines and other unexploded ordnance in the area to open up the use of land. It also provides mine risk education to reduce injuries, and has been present in the region since 2007.
