The fighting in Syria has again spilled over into Lebanon, where one Hezbollah fighter and several Syrian rebels were killed in clashes near the eastern Bekaa Valley on Sunday.

It came as the Syrian government forces, backed by many Hezbollah fighters, continued their three-month battle to regain the strategic Syrian town of Qusayr.

The International Red Cross says it believes thousands of civilians are still trapped there.
