A nother U.S.-led coalition strike in Raqqa province has killed 12 women, the Syrian Observatory for Human Rights said Monday.
The Britain-based activist group said the strike Sunday afternoon hit vehicles carrying farmworkers home from fields in the east of the province.
The activist group said it believed the strike had been carried out by the U.S.-led coalition fighting ISIS in Syria and Iraq.
The Observatory relies on a network of sources inside Syria and says it determines whose planes carry out raids according to their types, locations, flight patterns and the munitions used.
ISIS has lost swathes of the territory it once held in Raqqa province, though it still holds Raqqa city and some areas to the east.
A U.S.-backed alliance of Kurdish and Arab fighters known as the Syrian Democratic Forces is battling towards Raqqa city, the extremist group's most important remaining Syrian bastion.
The U.S. military said in May that coalition strikes in Syria and Iraq had "unintentionally" killed 352 civilians since it launched operations against ISIS in 2014.
Rights groups say the actual figure is much higher.

The regime President Bashar al-Assad said on April 22 that his country had information that Jordan is planning to send its troops into southern Syria in cooperation with the United States, accordng to Russian state-owned Sputnik.
“We have this information, not only from mass media, but from different sources,” Al-Assad told Sputnik, who interviewed him earlier this week. “You know that we have the same tribes and same families on both sides of the borders,” he told Sputnik’s reporter.
He also said that Amman “had been always part of the American plan” against Syria, claiming that Jordan is not an independent state, but instead carries out the plans imposed on it by the United States.
Mass media previously reported political sources in Amman speaking about Jordanian-American-British operations to be launched against terrorist organisations operating near the northern Jordanian borders with Syria.
The operation that Al-Assad expects comes after monitoring repeated movements of ISIS in areas about 20 kilometres from the Al-Raqban area on the Jordanian borders
