COLUMBUS, Ohio (AP) - The White House says it is "horrified" by reports that more than 100 people were executed Thursday in a western Syrian town.
White House spokesman Josh Earnest says those responsible for serious human rights and international law violations must be held accountable.
The State Department has cited reports Syrian President Bashar Assad's regime and pro-government forces destroyed Bayda, Syria, with mortar fire, then stormed the town, executing entire families.
Earnest wouldn't comment on an overnight airstrike Israeli warplanes carried out around the Syrian capital. The strike was the second attack by Israelis in three days. Officials say it targeted a shipment of advanced, Iranian-made missiles believed to be bound for Lebanon's Hezbollah militants.
Sen. John McCain tells "Fox News Sunday" that Syria has crossed another "red line" in transferring weapons to U.S. foes. McCain is not advocating U.S. ground forces go into Syria, but he says the United States should use its military might from afar.
Earnest spoke with reporters aboard Air Force One inflight from Washington to Columbus, Ohio.
