Two rockets hit a Hezbollah district of Beirut on Sunday, injuring at least five, as tensions from Syria are running at an all-time high. The rocket attack came just one day after Lebanon’s Hezbollah leader pledged to assist Syrian President Bashar al-Assad in the bloody civil war, and dozens of Hezbollah militants are believed to have been killed in recent fighting in Syria. An unnamed Lebanese security source told the AFP that the missiles were Grad rockets, a Soviet-style weapon. At least 40 people reportedly died in fighting in Qusayr, Syria on Saturday, one of the worst days of fighting since the beginning of the civil war. One activist told Al Jazeera that “an average of 40 shells per minute” hit the strategic town, which links Damascus to the Mediterranean Sea.
