The British Embassy in Sudan's capital has re-opened to the public, four days after it was closed because of a possible terrorist threat.

The embassy said in a statement Thursday that "additional security" has allowed it to resume normal consular and visa services.

The statement also thanked the Sudanese government for its cooperation.

Earlier this week, the government said it had broken up a plot to attack several Western diplomatic missions in the capital, Khartoum.

The state news agency reported that police had arrested eight Sudanese men and confiscated arms and explosives.

The British Embassy has advised British citizens to avoid travel to Khartoum.
