At least three people have died in bomb attacks on two minibuses near the Lebanese Christian mountain town of Bikfaya.
A further 20 people were injured in the attack, 24km northeast of the capital Beirut.
Most of the casualties were on the buses, which were carrying people to work in Beirut from the village of Ain Alaq near Bikfaya.
When the first bomb exploded, the driver of the second bus stopped and got out. His own bus then blew up.
The Interior Ministry said early information was that the bombs had exploded inside the minibuses.
A government source said the possibility of suicide bombings had not been ruled out.
Bikfaya is the home town of former President Amin Gemayel, whose son Pierre was assassinated by gunmen in November.
Tension has been running high in Lebanon since street clashes last month between supporters and opponents of the Western-backed government in which nine people were killed.
And the attacks occurred a day before the second anniversary of the assassination of former Lebanese Prime Minister Rafik al-Hariri.
Pro-government groups had planned a mass rally in Beirut's Martyrs Square tomorrow to mark the killing, despite fears of friction with opposition supporters camped nearby as part of a campaign to topple the anti-Syrian government.
