Occupied Jerusalem A Palestinian from the militant group Hamas was shot dead in the West Bank hours after the discovery of the bodies of three Israeli teenagers who were abducted over two weeks ago, Israel’s military said Tuesday.

Eyal Yifrah, 19, Gilad Shaar, 16, and Naftali Fraenkel, a 16-year-old with dual Israeli-American citizenship, disappeared on June 12 while hitchhiking home. The teens’ bodies were found Monday.

A Defense official said based on the investigation that the teens were shot soon after they were abducted. He spoke anonymously in line with protocol as the investigation is still ongoing.

Israeli Prime Minister Benjamin Netanyahu has said Hamas kidnapped the three and “will pay.” Hamas, which has kidnapped Israelis in the past, has praised the abduction of the teenagers but not taken responsibility for it.

The man killed Tuesday was the first casualty since the bodies were found.

A military spokesman said aircraft struck 34 targets across the Hamas-controlled Gaza Strip overnight as well. In an operation codenamed “Brother’s Keeper,” Israel dispatched thousands of troops across the West Bank in search of the youths, closed roads in the Hebron area and arrested some 400 Hamas operatives throughout the territory.

The search ended Monday afternoon with the discovery of the bodies under a pile of rocks in a field north of Hebron.

Defense Minister Moshe Yaalon issued a statement Tuesday vowing to find those behind the killings. “We see Hamas responsible for the kidnappings and murders. We will continue to pursue the murderers of the teens and will not rest until we lay our hands on them,” he said.

Israel has said two well-known Hamas operatives from Hebron are the primary suspects. The men, Marwan Qawasmeh and Amer Abu Aisheh, have not been seen since the teens went missing, and military officials said the search for them would continue.
