Americans were possibly kidnapped and killed in Israel during Hamas’ massive terrorist attack, Secretary of State Antony Blinken confirmed on Sunday.

Blinken assured the U.S. is working ‘overtime’ to look into reports claiming Americans were murdered in the heinous attack by Palestinian terrorists.

‘Is there any indication that Americans were either killed or kidnapped by terrorists?’ CNN‘s Dana Bash asked Blinken.

‘Yes, we have reports that several Americans were killed. We’re working overtime to verify that,’ President Joe Biden‘s top State Department official replied.

He added: ‘At the same time, there are reports of missing Americans. And, there again, we’re working to verify those reports.’
