Washington (CNN) - As tensions between Israelis and Palestinians ramp up, the United States must begin shuttle diplomacy, according to Sen. John McCain of Arizona.
One of the top Senate Republicans, McCain argued that Secretary of State John Kerry should go to the region and initiate a dialogue between the two sides.

"This thing is in danger of spiraling out of control. There's a whole lot of reasons for it, but right now, this is a time where the United States could play a constructive role," the former presidential candidate told CBS' Bob Schieffer.
Tensions escalated this past week after the bodies of three Israeli teenagers were found in the West Bank and a Palestinian teenager was abducted and slain in what officials suspect was a revenge killing. An American teenager, who was a cousin of the Palestinian, was later beat and detained by Israeli security forces at a protest following the funeral. He was released Sunday and placed under house arrest, with bruising around his eyes.
"When you start killing children, you set yourself on a path that is hard to reverse," said Sen. Lindsey Graham, R-South Carolina, on CBS’ "Face the Nation."
He agreed with McCain, calling on the United States "to engage and get the parties back into their corners."
The Obama administration has condemned the latest incident involving an American teen Tariq Khdeir.
"We are profoundly troubled by reports that he was severely beaten while in police custody, said State Department spokeswoman Jen Psaki in a statement, adding, "We are calling for a speedy, transparent and credible investigation and full accountability for the apparent excessive use of force."
But Graham argued that Israel will be quick to account for any mistakes and that Palestinians may not.
"One thing about Israel, they will try to investigate, I think, and bring somebody to justice," he said. "The other side is not very good at that."
