Hamas have admitted kidnapping three young people.
Meanwhile a senior Hamas leader, Saleh Arouri, told a conference in Turkey the group carried out the kidnapping and killing of three Israeli teens in the West Bank in June - the first time anyone from the Islamic militant group has said it was behind an attack that helped spark the current war in the Gaza Strip.
"It was an operation by your brothers from the al-Qassam Brigades," he said, saying Hamas hoped to exchange the youths for Palestinian prisoners held by Israel.
Hamas has repeatedly praised the kidnappings, but Arouri, the group's exiled West Bank leader, is the first member to claim responsibility.
The kidnappings on June 12, along with the discovery of the youths' bodies two weeks later, sparked a broad Israeli crackdown on Hamas members throughout the West Bank.
Hamas responded with heavy rocket fire out of the Gaza Strip, leading Israel to launch an aerial and ground invasion of the territory.
