Ethiopian rebels used an explosive device to attack the home of a family mourning the death of a relative killed in a rebel assault earlier in the week, a government spokesman said Friday. The blast killed one person. The explosion occurred Thursday in the eastern town of Jijiga, said government spokesman Zemedkun Tekle. He said the attack was carried out by rebels from the Ogaden National Liberation Front, who attacked a Chinese-owned oil exploration field in eastern Ethiopia on Tuesday, killing 65 Ethiopians and nine Chinese, according to AP. «The terrorists who have done the massacre have done this. This horrible incident has been committed by the ONLF,» he said. He did not know what caused the explosion. Officials of the rebel Ogaden National Liberation Front were not immediately available for comment. Bereket Simon, an adviser to Prime Minister Meles Zenawi, said the device was a grenade, but he did not know who was responsible for the attack. -- SPA
