Sporadic street fighting between Ethiopian troops and rebels trying to bring down Somalia's shaky government has killed 81 people in the past two days, the head of a local human rights group said on Monday. "The casualties ... were caused by Ethiopians using heavy artillery and tank shells in residential areas of the war-torn capital. We condemn this latest fighting," said Sudan Ali Ahmad, chairman of Elman Human Rights. Besides the 81 dead, 119 people had been wounded, he said. Elman tracks fatalities through hospitals and morgues.Yesterday's clashes broke out in rubble-strewn streets still littered with the uncollected bodies of the dead from the previous day's violence. Witness Aden Shire said the Ethiopians seemed to be searching for the bodies of fellow soldiers killed the previous day.
