Some parts of the capital, Beirut, are exclusively Shia Muslim, as is most of the south of the country. This is where the Shia Hezbollah group (backed by Shia-dominated Iran) is dominant. Another Shia stronghold is the Bekaa Valley, which Hezbollah has used as a staging post for its forages into Syria to support government forces there. Other towns are overwhelmingly Sunni Muslim. For example, Tripoli, in the north, is thought to be 80 percent Sunni, but it also has a sizable Alawite minority, and given the Sunni-Alawite tensions next door in Syria, this has led to sporadic bouts of fighting.
