Two Russian pilots operating in Sudan's western region of Darfur have been abducted by unknown gunmen, an army spokesman said on Monday.
The pair were seized in Nyala, capital of South Darfur state, on Sunday, spokesman, Mr Sawarmi Khaled Saad, told AFP.
"Two Russian pilots were kidnapped by a small armed group in a section of Nyala," Saad said. "We have closed off all access routes (around Nyala)."
The kidnappings mark the second abduction of foreigners in Darfur this month.
On August 14, two Jordanian police advisers deployed with the joint UN-African Union peacekeeping force police were kidnapped by gunmen but released a few days later.
