BAIDOA (Reuters) - Ethiopia pulled its last soldiers out of Somalia on Monday after a more than two-year intervention to combat an Islamist movement in its Horn of Africa neighbour, officials on both sides said.
The departure of Addis Ababa's roughly 3,000 troops starts a new era for Somalia, which has suffered 18 years of conflict.
Predictions the power vacuum would herald more bloodshed were confirmed with immediate violence in Baidoa, the seat of Somalia's parliament which Ethiopian troops left overnight.
Clan militia and local police looted the empty bases, with two people dying from shooting during the melee, witnesses said.
Insurgents then hurled a grenade at government soldiers near a bus-stop, prompting return fire. At least three people were killed and eight others injured in that incident, locals said.
Somalia's parliament, meeting in Djibouti due to insecurity at home, voted to double its size and invite 200 members of the moderate Islamist opposition to join the expanded body.
International players including the African Union and United Nations are pushing for a unity government as the only option for peace in the country of about 10 million.
"This morning we voted to make the addition to the federal parliament," said Ali Ismail, a member of parliament.
The vote means that Somalia's parliament would consist of the existing 275 members, 200 from the opposition Alliance for the Re-Liberation of Somalia (ARS) and 75 seats to be filled by other opposition members at a later date.
In Addis Ababa, Ethiopian officials confirmed the complete pullout of their troops, but said they would maintain a heavy presence along the long border with Somalia.
The Ethiopians entered Somalia to chase a sharia courts movement out of Mogadishu at the end of 2006. The offensive sparked an Islamist-led rebellion, fighting that has killed at least 16,000 civilians and a humanitarian disaster.
PRESIDENTIAL POLITICS
Somalia's weak, Western-backed government had depended on the Ethiopians for military support, and is now exposed to an array of Islamist opposition groups. The Islamists have, however, been fighting among themselves in recent weeks.
In Baidoa, residents already suffering from a drought and food shortages braced for a possible Islamist assault on a town the insurgents have long wanted to control.
"We are afraid thirst or fighting will kill us," said mother-of-eight Fatuma Ali, outside her closed store.
"We do not know where to run."
Somali government spokesman Abdi Haji Gobdon said the remaining Ethiopian troops pulled out of Baidoa on Sunday night before heading further west towards the border.
"The Ethiopians have fulfilled their promise. Their last troops crossed the border this morning," he said.
Meeting hundreds of Somali politicians in Djibouti, the United Nations' envoy Ahmedou Ould-Abdallah and other international players are also pushing for the election of a new president this week. But legislators said they may vote to delay that to allow more time for talks on enlarging parliament.
Under the constitutional charter, a new Somali president should be chosen by parliament within 30 days of the resignation of former President Abdullahi Yusuf, who quit on December 29.
The international community hopes a more inclusive Somali administration will be able to reach out to armed groups still fighting the government and African Union peacekeepers.
The more militant Islamist wing of the ARS, based in Eritrea, has so far refused to take part in the peace process. So have fighters in the hardline Islamist group Al Shabaab, who want to impose their strict version of Islamic law in Somalia.
