Peacekeepers attacked in Darfur

The peacekeeping force will be the biggest in the world

Armed men have ambushed a peacekeeping supply convoy in Sudan's Darfur region.

Unconfirmed reports from the region said the attackers were Sudanese government troops who mistook the convoy for rebels.

They were carrying fuel and food to a joint United Nations-African Union outpost in the West of Darfur.

A driver was seriously wounded in the attack - the first time the new peacekeeping operation has come under fire since the UN took over last week.

A spokesman for the United Nations-African Union mission (Unamid) said they were still investigating the incident and could not confirm the identity of the attackers.

No one was immediately available for comment from the Sudanese government.

Tensions have been escalating in the area over the last few weeks.

There have been violent clashes between the Sudanese government and rebel groups.

Neighbouring Chad has been accused by Khartoum of bombing villages in the area.

Unamid is due to become a 26,000-strong force but for the moment has just 9,000 troops.

At least 200,000 have been killed and two million forced from their homes in the five-year conflict.
