The US justified the strike saying its planes had acted to defend US-backed forces seeking to capture Raqqa, the Islamic State stronghold in northeast Syria, 9news.com reported.
On Sunday, a USA jet shot down a Syrian Su-22 fighter-bomber near the city of Tabqa.
The Britain-based Syrian Observatory for Human Rights, which tracks Syria's war, said government forces expanded their presence in Raqqa province by capturing from IS the town of Rasafa. The truce was meant to be extended but now appears to have collapsed.
Fighting and bombardment also resumed early Tuesday in the contested city of Daraa and nearby areas where a 48-hour truce went into effect on Saturday.
