Syria denied Monday a report that its forces have been using cluster bombs in its civil war.
"The General Command of the Army and the Armed Forces stressed on Monday that the misleading media outlets have recently published untrue news claiming the Syrian Arab Army has been using cluster bombs against terrorists," the government's term for rebels, the state-run Syrian Arab News Agency reported.
"In a statement, the General Command said the Syrian Army does not possess such bombs, stressing that those news (reports) are untrue and come in the framework of misleading media which is aimed at diverting the public opinion from the practices of the armed terrorist groups against civilians."
The report came a day after the publication of a human rights report that accuses the Syrian air force of using Russian-made cluster bombs.
Citing videos and witness accounts, Human Rights Watch said Syrian government forces were using the bombs. The report says the cluster bombs are Soviet-made, but it also says it's unclear how or when Syria may have acquired them.
"Syria's disregard for its civilian population is all too evident in its air campaign, which now apparently includes dropping these deadly cluster bombs into populated areas," said Steve Goose, arms director at Human Rights Watch. "Cluster bombs have been comprehensively banned by most nations, and Syria should immediately stop all use of these indiscriminate weapons that continue to kill and maim for years."
Russia questioned the report's veracity. "There is no confirmation to this," Foreign Minister Sergey Lavrov said, according to Russia's state-owned RIA Novosti news agency. "There are loads of weapons in this region, including in Syria and other countries of the region, and arms are supplied there in large quantities and illegally."
The bombs are particularly dangerous because they explode in the air, sending dozens or hundreds of smaller bombs over an area the size of a football field, Human Rights Watch said.
"These bomblets often fail to explode on initial impact, leaving duds that act like landmines and explode when handled," the group said.
More than 70 countries have signed a treaty banning the use of cluster bombs; neither Syria nor the United States is among them.
"Cluster munitions have demonstrated military utility," the U.S. State Department says on its website. "Their elimination from U.S. stockpiles would put the lives of its soldiers and those of its coalition partners at risk. Moreover, cluster munitions can often result in much less collateral damage than unitary weapons, such as a larger bomb or larger artillery shell would cause, if used for the same mission."

Turkey searches Syria-bound plane
For the second time in a week, Turkish officials on Monday searched a civilian plane that had been headed to Syria.
Armenian and Turkish diplomats told CNN that an Armenian cargo plane that had been en route to Aleppo stopped first on Monday morning in the Turkish city of Erzurum for an inspection of its cargo.
The move appeared to be part of Turkey's enforcement of a newly adopted blockade against the Syrian government.
Unlike last week's grounding of a Syrian passenger plane flying from Moscow to Damascus, Monday's airplane inspection appeared to have been agreed to ahead of time by Armenian and Turkish authorities.
After the search, which lasted at least five hours, the Armenian cargo plane was allowed to continue to Syria.
"The plane is transporting humanitarian aid to Syria and its stop in Turkey was planned," Armenian Foreign Ministry spokesman Tigran Balayan told CNN in an e-mail.
"The Turks, from our perspective, are taking a measured and appropriate posture with regard to these things," U.S. State Department spokeswoman Victoria Nuland told reporters.
