Naftali Fraenkel's uncle Yishai said that the three kidnapped boys were still alive according to the information given to the families by security forces, Channel 2 reported Friday.
"Of course I can't tell you anything, but I can say that the indications we're receiving - on the basis of intelligence and not just religious faith - is that the boys are alive," Fraenkel was quoted as saying in a radio interview.
"In defense of the security system, it's important to say that almost from the start of the incident, there have been representatives in each of the families' homes 24/7," he added. "The immediate family of course know more than what's going on in the media."
Also on Friday, Prime Minister Binyamin Netanyahu met with the parents of Naftali Fraenkel, Eyal Yifrah, and Gil-Ad Shaer at his home, Channel 2 reported.
They were expected to discuss the ongoing operation
in the West Bank to find their kidnapped sons, who have been missing for eight days.
This was the first meeting between the prime minister and the boys' parents.

The prime minister said that the main goal of the operation and intelligence activities currently being conducted is to bring the boys home.
"We are investing enormous effort to get to the boys," he said, adding that forces in the field have been increased.
