No casualties were reported in Al-Qasr, The Daily Star of Beirut said. Two people were killed in the village and in nearby Hawsh al-Sayyed Ali by a similar attack.
Syrian rebels say Hezbollah in Lebanon has been supporting Syrian President Bashar Assad and that the rockets are aimed at Hezbollah targets. Hezbollah says it is only defending Lebanese living near the border.
