The Syrian military announced Monday that the seven-day ceasefire negotiated by the United States and Russia is over, charging that rebel groups undermined the truce without saying if it would be reinstated.
Syria’s military command said in a statement that "armed terrorist groups" repeatedly violated the provisions required under the agreement 300 times, and accused rebels of using the truce to rearm while attacking government-held positions, Reuters reported.
The military said the rebels squandered a "real chance" to end the country’s civil war, which is now in its sixth year. It is unclear whether the truce will be renewed.
Opposition fighters and activists have accused Syrian President Bashar al Assad’s regime of violating the agreement.
The United Nations’ special envoy for Syria, Staffan de Mistura, said last week the Syrian government prevented humanitarian aid from reaching besieged areas, which was a primary provision of the deal.
The truce brokered by Secretary of State John Kerry and his Russian counterpart Sergey Lavrov went into effect last Monday and intended to suspend the civil war for a week. The U.S. military was to subsequently begin intelligence sharing with Moscow on Islamic State and other jihadist targets in the country, though this provision may have been jeopardized over the weekend.
The ceasefire came under strain on Saturday after the U.S.-led coalition killed at least 62 Syrian soldiers in a strike on an army post in eastern Syria.
Assad called the raid on his forces a "flagrant aggression" that proved the U.S. and forces fighting against his regime were "increasing support for terrorists," the state-run new agency SANA reported Monday.
The U.S. military acknowledged that it may have mistakenly hit Syrian troops while carrying out a strike against ISIS.
The U.S. and Russia brokered another ceasefire deal in February to briefly end the fighting across the war-torn country, but that agreement collapsed.
Syria’s civil war has killed 430,000 people since 2011, according to some estimates, and has displaced millions more from their homes.
