UN employee killed in Guinea

The United Nations says an employee of its refugee agency, the UNHCR, has been killed in a suspected rebel attack in the west African state of Guinea.

The UN says said the employee who was from Togo had his house set on fire during the attack, which happened in the town of Macenta.

Another UN worker who is from Ivory Coast is missing.

Tension has been high in the region following attacks by suspected rebels near Guinea's borders with Sierra Leone and Liberia.

The government has blamed refugees from the two countries for aiding the rebels and told them to leave.

In its latest statement, Liberia has said it cannot continue to guarantee the safety of Guineans in Liberia if the Guinean government continues to deny its aircraft landing rights to evacuate Liberian refugees.
