Ali Yasin Gedi, of Somali human rights group Elman, said many people had fled the town where allies of the government fought to drive out驱赶 Islamist rebels.

The pro-government Ahlu Sunna group is said to have recaptured the strategic town from al-Shabab militants¹.

Somalia has not had a functioning national administration since 1991. Its UN-backed government controls only a few parts of the country.

'Most violent yet'

Mr Gedi said his information was based on conversations with his organisation's workers in the town, 500km (310 miles) north of the capital, Mogadishu摩加迪休.

He told the BBC that some people had been taking the wounded to hospitals elsewhere in the region.

"Our monitoring office has confirmed that most of the casualties人员伤亡 were from the warring factions内功，派系, but some civilians⁴ were also killed," he said.

"Many people who fled from the town have not returned yet and they are in the outskirts市郊，郊区 of the town without shelter and the sun is extremely hot."

One resident, Hussein Moalim Mahad, told AFP news agency the fighting had been "the most violent ever seen in Dhuusa Marreeb".

Local chief Abdulahi Gedi said he had sent out two teams to collect bodies lying inside and outside the town.

Unverified reports say al-Shabab has been spotted⁶ regrouping in areas outside the town.

It is the first fighting in the area, which has been controlled by Ahlu Sunnah since a year ago when they defeated al-Shabab.
