Fighting in Syria is spilling into Lebanon as the regime's forces launch attacks against rebels hiding out over the border.
The village of Wadi Khaled, on the northern tip of Lebanese territory, has been hit several times by rocket fire and bullets from the Syrian, prompting hundreds of residents to flee.
"We've sent our children to go and stay with their grandparents, it’s too dangerous for them here," Ahmed al Waraidi said, pointing to the hole where a bullet hit one of the walls of his house.
The building next door - his new home under construction - was damaged by a rocket fired from a Syrian tank which smashed down part of the second floor.
"Everyone is too afraid to go out at night," another resident said. “We don’t just hide in our homes we hide underneath our homes."
The dusty, main street in Wadi Khaled comes to a sudden end just after the last house in the village, where it is blocked with concrete slabs.
Beyond the barricade is Syria, where the conflict is raging in villages close to the border - not just within ear shot, but within sight.
"We can see everything happening very close to us and people are very frightened," resident Abu Fadi said.
The nearest Syrian houses are a short walk away across a stream, and above them on a hillside a Syrian government tank could be seen.
The regime's forces have fired over the border to try to target rebels from the Free Syrian Army who are using Lebanese territory to re-group and re-arm.
In one derelict building nearby, a small group of young fighters were slumped on mattresses on the floor.
"Last night we were fighting in Syria and one of my friends was wounded, we tried to get him back over the border but he died," one of them said.
A 21-year-old said he had seen at least 20 of his friends die in battle in the past few months.
Their commander, still limping from a bullet wound in his leg, claimed to have hundreds of fighters operating from Lebanon but called for the world to send money so they could buy more weapons.
"We have just a few guns and not enough ammunition, and the grenades cost \$55 each,” he said pointing to the only grenade they seemed to possess, its pin taped down for safety.
The rebels say they are being supported by some of the local residents in Lebanon, despite their presence triggering Syrian government attacks.
The Lebanese government has officially complained about the cross border assaults, but has kept its own forces well away from the northern dividing line and has not attempted to chase down the rebels.
Lebanon, officially still a supporter of the regime, is desperate to stay out of the conflict, fearing it could re-ignite ethnic and religious tensions at home.
