All parties in Somalia's conflict have carried out rights abuses including executions, rape and torture, Amnesty International said on Tuesday, adding there were reports Ethiopian soldiers had slit civilians' throats.
Mogadishu's entire population is scarred from witnessing or suffering such abuses, as well as enforced disappearances and beatings, it said in its 32-page report.
Somali government troops and their Ethiopian allies have been battling Islamist-led insurgents since early last year.
Yet the real scale of the rights crisis remained unknown because international aid agencies were under pressure not to expose the abuses they witnessed, Amnesty said, and local journalists were often silenced by threats.
The interim government has largely failed to impose its authority on the Horn of Africa country of 8 million people, torn apart by inter-clan violence and vulnerable to cycles of drought, flooding and now skyrocketing food prices.
The Ethiopian and Somali governments have frequently denied committing rights abuses in their fight against what they call al Qaeda-backed terrorists. Prime Minister Nur Hassan Hussein has said government troops have the right to defend themselves.
However, Somali lawmaker Awad Ahmed Ashareh said the Ethiopian soldiers should be replaced.
"We are requesting that the international community gives an order for Ethiopia to leave and bring other forces," he told Reuters at the launch of Amnesty's report in Nairobi.
Ashareh called for an international court to be established to prosecute human rights abuses in Somalia.
Many Somalis living in southern and central areas say life is worse now than when dictator Mohamed Siad Barre was overthrown by warlords in 1991, plunging the country into lawlessness. Up to 1 million Somalis are refugees in their own land, while an estimated 6,500 civilians were killed last year.
