Beirut\Damascus- Syria's conflict spilled further into Lebanon on Saturday when mortar fire from Syria hit villages in the north, killing five people after rebels crossed the border to seek refuge, residents said.
At least three people have been killed and nine injured in northern Lebanon in shelling from across the Syrian border, local officials and residents told CNN.
The Lebanese state-run National News Agency said two RPG shells, launched from inside Syria, crossed the border and exploded in the town of Wadi Khaled, killing two and injuring two others.
A Lebanese security official told AFP that three people had died, but this could not be confirmed.
"A woman was killed in the early morning when a rocket landed on her house in the border region of Wadi Khaled," the security source said, adding that "the rocket came from Syrian territory."
"Several hours after, two Bedouin women were killed when shells landed on their tents in the same area," according to the source.
Residents of Lebanon's Wadi Khaled region said several mortar bombs hit farm buildings five to 20 km (3 to 12 miles) from the border at around 2 a.m on Saturday. Also at midday, villagers reported more explosions and said they heard gunfire close to the border.
In the village of al-Mahatta, a house was destroyed, and few were killed and wounded, family residents told Reuters.
Two Bedouins were killed in the village of Hishe, which straddles a river demarcating the border, when two rocket-propelled grenades fired from within Syria hit their tent, according to local residents.
Lebanon's army confirmed one of the deaths and said several Syrian shells had landed in Lebanese territory, but had no further information. Lebanese President Michel Suleiman issued a statement regretting the deaths and promising an investigation.
The attacks took place in the Wadi Khaled region, where both Syrian armed rebels and civilians have taken refuge from the violence at home.
The Wadi Khaled region, about 185 kilometers from Beirut, encompasses areas of southern Syria and northern Lebanon and has been the site of frequent illegal border crossings.
There have recently been clashes between armed men on the Lebanese side and the Syrian military.
There are fears the Syrian conflict will spread to neighboring countries. Like Syria's other neighbors - Turkey, Iraq and Jordan - Lebanon has absorbed thousands of refugees fleeing from the violence.
