Beirut: Two rockets have hit a district in the southern part of Lebanon's capital, wounding at least five people.
Initial reports said one of the rockets landed in the Mar Mikhael district in Beirut on Sunday, while the second fell on a car exhibit on the street.
Lebanon's state agency said security forces were looking for a third rocket that fell but did not explode.
Marwan Sharbel, the country's interior minister, inspected the scene where the rockets fell, saying they were fired from the southeastern side of the area but that it was too early to know who fired them.
It was an act of "sabotage", he said.
Tensions have been running high in Lebanon as Syrian rebels have threatened to retaliate against the Hezbollah group for sending fighters to assist the forces of Syrian President Bashar al-Assad in the battle to end a two-year revolt against his rule.
Sunday's attack came a day after a speech by the Shia armed group's leader Hassan Nasrallah, in which he committed to fighting in Syria's conflict.
Al Jazeera's Rula Amin, reporting from Beirut, said security forces surrounded the area where the rockets fell but have yet to provide more information on the attack.
"The attack does not come as a surprise and security forces had already been heavily deployed in the area in anticipation for any violence," she said.
