Activists say the death toll from Syrian airstrikes on the Islamic State group's main city of Raqqa has risen to at least 95 people.
The Britain-based Syrian Observatory for Human Rights said Wednesday that Tuesday's attacks on an industrial area and popular market near the city's museum also injured at least 120 people.
The Syrian Observatory, which has documented casualties throughout Syria's nearly four-year civil war, said the dead include at least 52 civilians. It did not specify how many militants, if any, were killed.
Syria has battled since March 2011 against a range of groups opposed to President Bashar al-Assad's rule, while Islamic State fighters have seized territory in eastern Syria as part of their self-declared "caliphate" that stretches into neighboring Iraq.
Earlier this month, the Islamic State group released a video showing militants beheading 18 men described as Syrian soldiers.
