The ceasefire between the Syrian opposition and the regime forces collapsed in Syria's northwest only one day after its announcement, the UK-based Syrian Observatory for Human Rights (SOHR) said.
The ceasefire collapsed, in the village of Fuaa, near the Lebanese border.
The original ceasefire was supposed to cover Fuaa, Kafreyya and the city of Zabadani, along with numerous other villages.
Syrian regime violated the ceasefire and attacked the opposition held village of Taftanaz nearby Fuaa with deadly barrel bombs on Saturday, the opposition then retaliated by firing mortar shells at the villages of Fuaa and Kafreyya.
Opposition statement claims regime barrel bombs killed 5 people in Taftanaz.
The collapsed ceasefire was UN-backed and confirmed on Friday, it was also supposed to last for 6 months. The agreement was between the Fateh army and the Syrian regime backed Lebanese Shiite militia of Hezbollah.
Hezbollah’s leader Hassan Nasrallah and Iranian officials also mediated and backed the ceasefire agreement. Past ceasefire agreements have similarly collapsed.
The ceasefire terms entailed allowing members of Syrian opposition coalition group Fateh army and their families to safely transfer out of Zabadani area near the Lebanese border to rebel held areas in northern Syrian city of Idlib.
Zabadani was one of last opposition strongholds in south Syria, but it has been sieged by the Syrian regime and Hezbollah forces for several months.
In exchange, approximately 10,000 pro-regime fighters and civilians from villages of Fuaa and Kefraya in the rebel-controlled northern Idlib province will be relocated to regime held areas in Damascus.
The Syrian conflict has been ongoing since March 2011, 240,000 people have been killed and millions have been displaced internally and internationally due to the conflict.
