Iran has signed a deal with Afghanistan to supply its neighbour with a million tons of fuel oil, petrol and aviation fuel a year, Iranian media reported without putting a value on the agreement. The accord was signed Monday by the Afghan trade and industry minister, Anwar Ul-Haq Ahady, and Iran's deputy oil minister, Alireza Zeyghami. Two-thirds of the export deal was for fuel oil, a category that includes diesel and fuel for agricultural, industrial and heating uses, according to Zeyghami. A quarter was for petrol and around 10% was jet fuel, he said. The agreement was announced as Iran is subject to Western sanctions against its oil and gas sectors over Tehran's controversial nuclear programme. The United States and Europe are poised to increase sanctions in coming weeks.
