Ethiopia is detaining "many" ethnic Somali Americans and Europeans on suspicion of terrorism links and participating in a separatist insurgency in the southeast of the Horn of Africa nation, the top regional official said Friday. Abdullahi Hassan, the most senior official in Ethiopia's Somali region, told reporters many of the foreign detainees were involved in "anti-peace" and "international terrorism" groups. Hassan refused to say how many detainees are held or say which European countries they come from, just that there were "many." He said their embassies had not been informed. The US Embassy in Addis Ababa, through spokeswoman Darragh Paradiso, said: "We have no information on American citizens being detained and are following up on this issue with the government of Ethiopia as we speak."
