Beirut, on Monday, in a shocking incident, eight suicide bombers attacked a Lebanese Christian village, which killed five people and injured dozens more, in the latest violent spillover of the five-year-old Syrian war into Lebanon.

Acording to the security sources, "it is believed that Islamic State was responsible for the bombings in the village of Qaa on Lebanon's border with Syria, but there was no immediate claim of responsibility."

A first wave of attacks involved four suicide bombers who struck after 4 a.m. (0100 GMT), killing five people, all civilians.

A second series of attacks, involving at least four bombers, took place in the evening as residents were preparing the funerals of those killed earlier.

Two of the four bombers blew themselves up outside a church, security sources said.

"It is clear from the pace of explosions that we have entered an episode from hell," Wael Abu Faour, the health minister, said.
