Three of the six Israelis arrested on suspicion of involvement in the murder of  Mohammed Abu Khdeir, 16, have confessed, according to an Israeli official speaking to the AP.

On Sunday, law enforcement officials arrested six male Jewish Israeli citizens in connection to the teenager's death. According to the autopsy report, Khdeir was burned alive by his assailants. Although officials haven't given a motive, a security official told the Washington Post that they believe the suspects acted with a "nationalistic" motivation following the kidnapping and murder of three Israeli teenagers. The suspects remain unnamed as of Monday morning. 

The deaths of four teenagers in the troubled region — three Israeli and one Palestinian — have prompted riots and airstrikes. Israel began bombing Hamas-controlled Gaza just hours after the Israeli teens' bodies were found (although Hamas denies involvement in the kidnappings and murders, Israel has publicly blamed the group for the deaths). Although the Israeli escalation was widely seen as retaliation for the murders, Israel's official reason for the airstrikes was an increase in rockets fired from Gaza into southern Israel over the past few weeks. 

Israel's response has been deadly for the group: according to Hamas's statement vowing retaliation, the strikes have killed seven of their militants. At least 20 rockets were fired back from Gaza to Israel in response to the airstrikes, the New York Times notes.
