BEIRUT (AP) — Russia will not stop selling arms to Syria, a top defense official said today, as Moscow stands by its longtime ally despite mounting international condemnation over the Syrian regime’s bloody crackdown on a 10- month-old uprising.

Russia’s Deputy Defense Minister Anatoly Antonov said his country is not violating any international obligations by selling weapons to Damascus.

“As of today there are no restrictions on our delivery of weapons,” he told journalists in Russia, according to the country’s state news agencies. “ We must fulfill our obligations and this is what we are doing.”

Moscow has been one of Syria’s most powerful allies — along with Iran — as Syria tries to crush the revolt against President Bashar Assad. The U. N. estimates that more than 5,400 people have been killed in the government crackdown.

Moscow’s stance is motivated in part by its strategic and defense ties, including weapons sales, with Syria. But Russia also rejects what it sees as a world order dominated by the U.S. Last month, Russia reportedly signed a $550 million deal to sell combat jets to Syria.
