A Darfur rebel group has claimed it has attacked a Sudanese oilfield in the Kordofan region, taking a Canadian and an Iraqi oil worker hostage, according to the BBC.

The group, the Justice and Equality Movement (Jem), said it attacked the facility which is run by a Chinese-led consortium in the Defra oilfield.

Jem said its action was a message to China to stop helping the Sudanese government with their war in Darfur. China is investing heavily in Africa, but it faces criticism for maintaining close links with the Sudanese government in Khartoum as international concern over the situation in Darfur has continued to rise.

The Canadians and the Iraqi both worked on the oilfield run by the Chinese-led consortium, the Greater Nile Petroleum Operating Company in Sudan’s Defra oilfield.

Jem said the Chinese company had one week to leave Sudan.

Somehow I doubt that they will leave, so the ugly politics of Darfur look set to get worse.
