Syrian rebels and Hezbollah 'exchange fire in Lebanon'

Hezbollah has been fighting alongside the Syrian army in the strategically important Syrian town of Qusair

A number of people have been killed in an exchange of fire between Syrian rebels and fighters from the Lebanese militant group Hezbollah, say reports.

Lebanese security sources said the clashes took place on Lebanon's side of the border, near the town of Baalbek.
Hezbollah is fighting alongside the army in Syria, but the clashes have rarely crossed onto Lebanese soil.
Meanwhile the Red Cross has said it is alarmed by the worsening situation in the besieged Syrian town of Qusair.
It has appealed for access to the town, which lies just 10km (6 miles) over the Lebanese border.
Thousands of civilians are believed to be trapped as pro-government forces - including Hezbollah fighters - battle rebels.
The office of UN Secretary General Ban Ki-moon also appealed to the warring parties to allow residents to flee.
Syrian state TV quoted Foreign Minister Walid al-Moualem as saying the Red Cross would be allowed in "as soon as military operations are over".
Reuters reported that Mr Moualem had expressed his surprise to Mr Ban about the international concern, saying there had been none when rebels took over the town last year.
Also on Sunday, a car bomb killed nine members of the Syrian security forces in the capital, Damascus, according to the British-based pro-opposition watchdog the Syrian Observatory for Human Rights.
The watchdog said the bomb had targeted a police station in the eastern district of Jobar, which has seen renewed clashes between government forces and rebels who are entrenched there.
