U.S airstrikes near Manbij, Syria on Thursday, may have resulted in more civilian casualties, the U.S. Central Command said.

“We can confirm the Coalition conducted airstrikes in the area in the last 24 hours,” the U.S. Central Command said in a statement.

That day, coalition military forces continued attacking ISIS in Syria and Iraq. Aircraft conducted 22 strikes in Syria, 19 of which were near Manbij and nine strikes in Iraq.

The U.S. Central Command said it will review any information about the incident, saying that it takes all measures during the targeting process to avoid or minimize civilian casualties or collateral damage.

On July 19, at least 56 civilians were killed in airstrikes near Manbij, Reuters reports.

From July 28, 2015 to April 29, 2016, U.S. airstrikes in Iraq and Syria have resulted in the deaths of 14 civilians, U.S. Central Command said in a statement. “We deeply regret the unintentional loss of life and injuries resulting from our airstrikes and express our sympathies to those affected.”
