MORE than 45 pick-up trucks armed with anti-tank guns, anti-aircraft weapons and heavy machine-guns arrived in the south-central Somali town of Baidoa on Wednesday to protect a shipment of shillings due to arrive. The battle-wagons are manned by militiamen loyal to warlord Mohamed Hussein Aidid and the currency thought to be heading to Abdulrashid Shire Ilqeyte, Aidid’s financier. Aidid, who has been in Baidoa for the past three weeks, had the shillings printed in Canada. Somalia has been without a government — or central bank — since the overthrow of dictator Mohamed Siad Barre in 1991, and various factions and warlords print their own money.
