...[Petronas] is facing accusations of violating a United Nations arms embargo by providing fuel to military aircraft that attack civilians in war-torn Darfur...But human-rights and arms experts say the company has provided fuel to Sudanese bombers and ground-attack aircraft in Darfur...Photos obtained by The Globe and Mail show a Petronas fuel truck at Nyala airport in Darfur on April 17, 2012, and Dec. 28, 2011, supplying fuel to An-26 and Su-25 aircraft of the Sudan Armed Forces (SAF). Antonovs are often used as improvised bombers in Darfur, and Su-25s often fire air-to-ground rockets in the region. The UN Panel of Experts on Sudan, authorized by the UN Security Council to monitor the embargo, has said that the supply of aviation fuel for military purposes is a violation of the embargo. “I have no hesitation in saying that Petronas is supplying fuel to SAF military aircraft,” said Mike Lewis, an aviation expert who served on the UN Panel of Experts in 2011.
