Hizbullah and Syrian rebels have reached an agreement involving a six-month ceasefire in three battleground Syrian towns, a monitoring group said Thursday.

Hezbollah leader Hassan Nasrallah said in an interview with the group’s al-Manar TV that increased Russian support for Assad included highly advanced weapons systems, warplanes and helicopters. Under the arrangement, up to 10,000 civilians will be allowed to leave the two towns and move to government-controlled territory further south. It was unclear whether the deal also permits the departure of combatants from Foua and Kefraya.

Situated about 12 kilometers (seven miles) from the Jdeida border crossing on the Damascus-Beirut highway, Zabadani is one of the last militant strongholds near the Lebanese border.

Sunni rebels attacked the two villages after government forces laid siege to Zabadani in July.

Shells apparently fired by rebel fighters hit the village of Fuaa in the province of Idlib on Saturday, the UK-based Syrian Observatory for Human Rights has said, after rebels blamed government forces for violating the ceasefire by dropping barrel bombs on an area nearby.

On Russia’s recent military build up in Syria, Nasrallah said that “several factors led to this decision”.

Citing “preliminary information”, the Observatory said the deal envisages the evacuation of women and children from Fuaa and Kafraya in return for the withdrawal of Zabadani’s rebels along with their families to the Idlib province. Turkey and Iran sponsored the deal, it added.

The United Nations says the militancy has displaced more than 7.2 million Syrians internally, and compelled over four million others to take refuge in neighboring countries, including Jordan and Lebanon.

Netanyahu said he was determined to stop arms deliveries to Hezbollah and accused Syria’s army and Iran of trying to create a “second front” against Israel.

However, the truce conditions would not force people to relocate, he added.

The Observatory director Rami Abdurrahman, whose group relies on a network of activists on the ground, also criticized attempts to large scale population transfer.
