Nairobi, Mogadishu - Gunmen have abducted two people working for the United Nations' mine action programme in Somalia, the BBC said Saturday.

Reports said that gunmen seized the two, believed to be Scandinavian, and a Somali aid worker after temporarily gaining control of a town in southern Somalia.

Nobody from the UN's mine programme in Somali or its coordinating office in neighbouring Kenya was available to confirm the reports.

Many aid workers have been abducted since the man believed to be al-Qaeda's top operative in the country, Aden Hashi Ayro, was killed in a US air strike on May 1.

The head of the UN refugee agency UNHCR's Mogadishu programme was kidnapped last weekend and is still being held.

Several other aid workers have been in the hands of gunmen for months and the World Food Programme has seen three of its drivers killed.

Ayro was the leader of Islamic militant group al-Shabaab, the armed wing of the Union of Islamic Courts (UIC). Al-Shabaab said it would target foreign troops and workers in revenge.

Militants have been waging a guerrilla war against government troops since the UIC was ousted from power at the beginning of 2007 with Ethiopian assistance.

The interim government has been unable to achieve stability in the Horn of Africa country that has been plagued by chaos and civil war since the ouster of dictator Mohamed Siad Barre 1991.

A peace deal was agreed between moderate Islamists and the government in early June, but al-Shabaab has not signed up to the agreement and has vowed to keep fighting until Ethiopian troops leave the country. (dpa)
