Israeli warplanes 'launch air strike in Syria'
US media reports suggest that Israeli warplanes have launched an air strike inside Syria, BBC reported.
The reports, quoting unnamed US officials, say the likely target was a weapons site. Some indicate the arms were to be sent to Lebanon's Hezbollah.
There has been no confirmation from the Israeli or Syrian government.
Meanwhile, President Barack Obama says he does not foresee sending US troops to Syria, amid concerns over the possible use of chemical weapons there.
Speaking on a visit to Costa Rica, Mr Obama reaffirmed that clear evidence that the Syrian government had used chemical weapons would be a "game changer", but that any response would not be rushed.
The US officials - speaking on condition of anonymity - say the Israeli air strike probably happened on Thursday or Friday, but the aircraft did not enter Syrian airspace.
An Israeli embassy spokesman in Washington declined to comment.
But the spokesman - quoted by Reuters news agency - added: "What we can say is that Israel is determined to prevent the transfer of chemical weapons or other game-changing weaponry by the Syrian regime to terrorists, especially to Hezbollah in Lebanon."
The Syrian ambassador to the UN said he was not aware of any Israeli attack against his country.
Meanwhile, Lebanon's National News Agency cited a Lebanese army communique as saying that "two Israeli warplanes breached the Lebanese airspace over the southern town of Rmeish" on Friday.
It said "the enemy warplanes flew in circular manner over all Lebanese regions, and then left."
Earlier this week, Israeli Defence Minister Moshe Yaalon acknowledged that Israel had launched an airstrike in January against a target inside Syria.
He said that the transfer of sophisticated weapons to radical militant groups like Hezbollah was a red line for Israel, and Israel had acted when it was crossed.
