Kurdish forces in the Syrian city of Hasakah have violated a ceasefire agreement they had struck with Syrian army forces hours earlier.
The Kurdish forces attacked the district of Nashwa in southeastern Hasakah early on Monday, according to Reuters.
According to Syria Now website, the Kurdish fighters set fire to governmental buildings in Hasakah on Monday.
Reports also said the forces had earlier seized control of the Ghwairan neighborhood in the northeastern Syrian city.
The Syrian army and popular forces have been engaged in clashes with the Kurdish militants to thwart their acts of sabotage in Nashwa and Ghwairan since Sunday.
Even though both the Kurds and the Syrian army have been battling the Takfiri Daesh terrorist group, clashes erupted between them on Wednesday.
The Syrian forces and the Kurdish fighters agreed on a Russian-brokered ceasefire in Hasakah on Sunday.
Syria has been gripped by foreign-backed militancy since March 2011. UN Special Envoy for Syria Staffan de Mistura estimates that over 400,000 people have been killed in the conflict.
The UN no more provides an official death toll for Syria.
