Ahead of his visit to Israel, US Secretary of State John Kerry responded to Monday's four terror attacks against Israeli citizens and addressed the purpose of his visit. 

"This is an effort to see if we can get some concrete steps in place – begin to build them, maybe – that could calm things down a little bit so people aren’t living in absolute, daily terror that they might be stabbed or driven into or shot trying to walk around their city," he said from Abu Dhabi.

"It happens almost every day over there and it's terrible, and too many Israelis have been killed and stabbed, and too many Palestinians," Kerry told reporters. "And there’s no excuse for any of the violence."
