The Lebanese army has strengthened security measures and set up checkpoints in the border region with Syria, media reports suggested.
Earlier this week, the Syrian ambassador to Lebanon, Ali Abdel Karim Ali, called on the Lebanese state to be "tougher" in controlling its borders with Syria in order to prevent the infiltration of "armed groups" to its territory.
"In Lebanon there are a haven for extremist groups in Lebanon. We urge the Lebanese state to keep an eye on this paradise," said the ambassador, referring to villages in northern Lebanon, on the border with Syria.
"The government and the authorities must respect the agreements concluded between Lebanon and Syria," he added, noting that security measures were "insufficient".
"We know they are trying to solve this problem, but we hope they will be more serious as the situation in Lebanon is very sensitive. Anything that threatens Lebanon's national security should be taken seriously as Lebanon and Syria are one ", said the diplomat.
The Syrian army continues its attacks on several cities, notably in the area of Deraa, cradle of the revolt in the south. These attacks come as Russia said it had no intention of changing its position vis-à- vis its Syrian ally.
This declaration came on the eve of the arrival in Syria of the head of UN humanitarian operations Valerie Amos. On Saturday, the UN and the Arab League envoy Kofi Annan is expected in Damascus.
At least 41 people were killed yesterday in violence, mainly during a major assault on the city of Hirak in the province of Deraa, reported the Syrian Observatory of Human Rights.
