Somalia ? Three days of fighting between Islamic insurgents and Ethiopian troops backing the government has killed at least 113 civilians, a local human rights group said Friday. The U.N. said hundreds of thousands of residents had fled.

Sporadic fighting between Wednesday and Friday had wounded 229 people, said Sudan Ali Ahmed, chairman of the decade-old Elman Human Rights Organization. He said his organization collected the figures from hospitals, local residents and its agents recording burials in the Mogadishu.

On Friday, the U.N. refugee agency revised its estimates of people who fled Mogadishu to 321,000 – more than one-tenth the total population of about 2 million.
