BEIRUT, Lebanon — Eight suicide bombers launched two waves of attacks on the Christian town of Al Qaa in northeastern Lebanon on Monday, killing at least five people and raising fears that violence from the civil war in neighboring Syria will further destabilize Lebanon, its fragile neighbor.

Four attackers blew themselves up in the town before dawn, killing five people and wounding a dozen others, according to local officials. Four more attacks took place at night as residents prepared for funerals to be held on Tuesday morning, wounding 11 more people, according to the state-run National News Agency.

Lebanon has so far managed to avoid large-scale violence, but the country has extensive political and sectarian ties with Syria and has struggled to insulate itself from the civil war. Some Lebanese have joined the fight across the border. Hezbollah, the powerful Shiite militia, is backing President Bashar al-Assad of Syria, and some Sunni Muslims have joined the rebels seeking to topple him.

The country has also taken in about 1.5 million Syrian refugees, whose presence has stressed government services and put pressure on the economy.
