Hezbollah guerrillas fought a deadly battle with Syrian rebels in Lebanon's eastern border region early on Sunday, security sources said, in the latest eruption of Syria's conflict on Lebanese soil. Sources said at least 12 rebels were killed in the fighting east of the Bekaa Valley town of Baalbek, but the toll would not be clear until bodies were retrieved from the remote and rugged border area. One Hezbollah fighter also died, they said.
Syria's two-year-old conflict has increasingly sucked in its smaller neighbour, with deadly fighting shaking the northern Lebanese city of Tripoli and rockets hitting the Bekaa Valley and southern Beirut.
Shia Hezbollah, which supports President Bashar al-Assad, is fighting alongside his army to drive rebels from the Syrian border town of Qusair, while Lebanese Sunni Muslim fighters have joined the anti-Assad revolt. The latest fighting took place near Ain el-Jaouze in a strip of Lebanese territory which extends into Syria, the sources said, and the rebels may have been ambushed as they set up rockets to fire into Shia areas of the Bekaa Valley.
Rebels have said they will carry out attacks inside Lebanon in response to Hezbollah's support for Assad's assault on Qusair, a strategic town for rebel weapons supplies and fighters coming into Syria from Lebanon.
The United Nations said on Saturday that up to 1,500 wounded people might be trapped inside Qusair and UN officials called for an immediate cease-fire to allow them to receive treatment. The International Committee of the Red Cross asked for access, saying it was ready to enter Qusair immediately to deliver aid.
But Syrian state television said Foreign Minister Walid al-Moualem told UN Secretary-General Ban Ki-moon by telephone on Sunday that the Red Cross would have to wait until military operations in the area were complete.
Moualem also expressed surprise at international concern over the fighting around Qusair, saying the world had been silent when rebels took over the town 18 months ago and that Syria was now clearing it of "terrorism", the television said. The Britain-based Syrian Observatory for Human Rights, which has a network of medical and security sources on the ground, said heavy fighting continued in the northern, eastern and southern outskirts of Qusair on Sunday.
Security Council diplomats said Russia, which along with China has shielded Assad diplomatically at the United Nations, blocked a council declaration of alarm on Saturday over the two-week siege of Qusair.
The draft statement urged forces loyal to Assad and rebels trying to oust him "to do their utmost to avoid civilian casualties and for the Syrian Government to exercise its responsibility to protect civilians".
It appealed to Assad's government "to allow immediate, full and unimpeded access to impartial humanitarian actors, including UN agencies, to reach civilians trapped in al-Qusair".
Moscow's move to block the statement highlights the deep chasm between Russia and Western nations on how to deal with the war in Syria despite joint efforts by Washington and Moscow to convene a peace conference on Syria.
French Foreign Minister Laurent Fabius suggested on Sunday that the conference could take place in July, echoing comments by officials in the Middle East. He said the Syrian government and the opposition must attend what he called "the last chance" for a negotiated solution.
