(Adds number of suicide bombers, background)

BEIRUT, June 27 (Reuters) - Four suicide bombers killed six people and wounded 19 others in an attack in a Lebanese village at the border with Syria on Monday, security sources said.

The attack at 4 a.m. (0100 GMT) targeted the mostly Christian village of Qaa, a few kms (miles) from the border. Three Lebanese soldiers were among the wounded, the sources said.

The mayor of Qaa, Bashir Matar, told Voice of Lebanon radio that all those killed were civilians.

There was no immediate claim of responsibility. Hezbollah's al-Manar TV said the attack was carried out by Islamic State militants.

Lebanon has been repeatedly jolted by militant attacks linked to the five-year-long war in neighbouring Syria, where the powerful Shi'ite group Hezbollah is fighting in support of President Bashar al-Assad.
