The Israel Security Agency released the identities of two suspects in the kidnapping of three teenage boys from Jewish settlements in the West Bank two weeks ago . `` The Israel Security Agency established less than a day after the kidnapping ... that Hamas was believed to be behind the June 12 abduction , the ISA said in a statement Thursday . `` Hamas activists from Hebron , '' Marwan Kawasmeh , 29 , and Amar Abu-Isa , 32 , were behind the abductions , the intelligence agency said . Both men have been arrested by Israeli security forces before , according to an ISA news release . Kawasmeh served a 10-month prison sentence . `` In his most recent investigation , in 2010 , ( Kawasmeh ) admitted to having been recruited to the Hamas military wing in the Hebron area in 2009 , '' ISA said . Abu-Isa was detained several times between 2005 and 2007 . Lt. Col. Peter Lerner of the Israel Defense Forces said Thursday that both men have `` a history of terrorist activity '' and both were `` suspects immediately after the kidnapping . '' The three teenagers , Gilad Shaar and Naftali Frenkel , both 16 , and Eyal Yifrach , 19 , were last seen around Gush Etzion , on the Israeli side of the West Bank barrier late on June 12 or early on June 13 , according to the IDF . After the release of the suspects ' identities , Prime Minister Benjamin Netanyahu responded with a comment directed at Palestinian Authority President Mahmoud Abbas . `` I now expect President Abbas ... to break his pact with the Hamas terrorist organization that kidnaps children and calls for the destruction of Israel . '' Previously Abbas had condemned the kidnappings and called on all sides to refrain from violence , according to an Israeli newspaper report earlier this month . Netanyahu blamed Hamas for the kidnappings almost immediately . A Hamas spokesman said in the days after the abductions that Netanyahu 's comments attributing blame were `` stupid and baseless . '' Israeli security forces have conducted an extensive search for the teens . Within days after the teens ' disappearance , Israeli soldiers had detained more than 150 Palestinian suspects . The military said Hamas leaders and operatives were among the suspects . As the search for the two suspects continues , the IDF and ISA said Thursday several other suspects are also being questioned `` for their personal involvement of the attack . ''
The Israel Security Agency also suspects in teens ' disappearance . It says ` ` Hamas activists '' are to blame . The two teenagers disappeared from the West Bank on June 12 . Netanyahu calls on Israel to take action .
