Two rockets hit a Hezbollah-controlled district in the southern part of Lebanon's capital on Sunday, residents said, wounding several people.
The attack may have been a response to a speech by the militant group's leader Hassan Nasrallah a day earlier, in which he committed to fighting in Syria's conflict on behalf of his ally President Bashar al-Assad.
