MOSCOW, April 5. /TASS/. Russia has filed no applications with the United Nations Security Council for an approval of sales of Su-30 fighter jet to Iran, hence, the United States’ threats to clock this deal is just a speculation, a well-informed source at the Russian foreign ministry told TASS on Tuesday.

"The Russian side has filed no applications with the United Nations Security Council for approval of sales of Su-30 fighter jets to Iran. There is no such item on the agenda," he said.

"The weapons embargo against Teheran exists no longer," the source said. "A new, authorization-based procedure of supplies of weapons and spare parts to Iran has been established. It is applicable to seven categories of the United Nations register of conventional arms. These categories include in particular warplanes, assault helicopters, warships, artillery systems, missiles, etc. In formal terms, their supplies are not banned either but a corresponding application is to be endorsed by the United Nations Security Council."

As for the S-300 missile systems, there are not on the above register, the source pointed. "No permits are needed for sales of such systems to Iran," he said. "It is not even necessary to notify anyone."

Earlier on Tuesday, Shannon, the U.S. Under Secretary of State for Political Affairs, said the United States will use its right to veto in the United States Security Council to block sales of Russia weapons, such as Su-30 fighter jets, T-90 tanks and combat helicopters, to Iran

"The sale of Su-30 fighter aircraft is prohibited under UNSCR 2231 without the approval of the UN Security Council and we would block the approval of any sale of fighter aircraft under the restrictions," Shannon told Foreign Relations Committee hearing.
