MOSCOW (AP) — Russia will block any attempt by the West to secure UN support for the use of force against Syria, Russia's foreign minister said Wednesday.

Foreign Minister Sergey Lavrov said Russia's draft of a UN Security Council resolution on the violence in Syria that circulated Monday was aimed at making it explicitly clear that nothing could justify a foreign military interference.

The Security Council has been unable to agree on a resolution since the unrest began in March because a strong opposition from Russia and China. In October, they vetoed a West European draft resolution, backed by the U.S.

Lavrov said Russia would reject any attempts at securing a UN sanction for a military interference in Syrian affairs.

"If some intend to use force at all cost ... we can hardly prevent that from happening," he said. "But let them do it at their own initiative on their own conscience, they won't get any authorization from the UN Security Council."

Lavrov also said that Russia doesn't consider it necessary to offer an explanation or excuses over suspicions that a Russian ship had delivered munitions to Syria despite an EU arms embargo.

Lavrov told a news conference that Russia was acting in full respect of the international law and wouldn't be guided by unilateral sanctions imposed by other nations.

"We haven't violated any international agreements or the UN Security Council resolutions," he said. "We are only trading with Syria in items, which aren't banned by the international law."

Lavrov accused the West of turning a blind eye to attacks by opposition militants and supplies of weapons to the Syrian opposition from abroad.

"They are dodging the main question — why we should keep silent about the extremist opposition's actions against administrative buildings, hospital, schools," he said, urging the West to use its contacts with the opposition to urge it to refrain from violence.

He said that arms supplies to the Syrian opposition are "unacceptable and absolutely counterproductive, because it only fuels more violence."
