Gunmen hold two UN workers in war-torn South Sudan

"We are extremely concerned about his well-being," Eddie Rowe, the WFP chief in South Sudan, said in a statement.

"WFP demands that his captors release our staff member unharmed."

It was not clear if the gunmen were from the country's feared national security or another group.

UNMISS said both the army and the government had told them they were "making all efforts to track down the abductors and secure the release of the two victims."

Aid workers have been targeted in the more than 10 month civil war.

In August, gunmen killed at least six South Sudanese staff members of international aid agencies.

The town of Malakal has changed hands several times in the ongoing civil war, but is now in government control.

Thousands of people have been killed and almost two million have fled fighting between government troops, mutinous soldiers and ragtag militia forces divided along tribal lines.
