A suicide bomber and three militants attacked a United Nations compound in western Afghanistan Saturday.

According to media reports, the men approached the entrance of the compound in a car. Three of the attackers got out of the vehicle and then the driver detonated a car bomb, destroying the gate.

The militants stormed into the compound firing their weapons, but were quickly killed by Afghan security forces.

The Afghan government has banned private security companies from working inside the war-torn country. This threatens to shut down or stall billions of dollars in development projects across the nation.

U.S. and other western diplomats were conducting intense negotiations with Afghan officials this weekend over President Hamid Karzai's decision to shut down private security contractors by Dec. 17. He claims the private guards are undermining his nation's army and police and wants Afghan security forces to take on the job of providing protection for the aid workers. Western officials argue that the hand-over must be phased in so projects are not disrupted.

Meanwhile, U.N. Special Envoy to Afghanistan Staffan de Mistura announced Sunday the U.N. will continue its work in the region, despite Saturday's attack.

"The U.N. will continue to maintain its presence and programs in Herat for the benefit of the population and in support of the Afghan authorities," De Mistura said in a statement.
