以色列搜寻被绑架少年时打死两名巴勒斯坦人

Israeli troops shot dead two Palestinians in the West Bank early Sunday in separate clashes that erupted as the military continues its search for three missing Israeli teenagers.

Israel says one Palestinian man was killed in the Nablus area after ignoring warning shots and approaching them in what was described as "a threatening manner."  The man's family told the French news agency the man was mentally challenged.  

Another Palestinian man was killed in gunfire in Ramallah, the Palestinians' administrative capital of the West Bank.

The three Israeli youths, one with a U.S. passport, disappeared on June 12 in the southern West Bank.  .

Israel has blamed the militant group Hamas for the abduction, but has no proof they were involved.  On Sunday, Israel Prime Minister Benjamin Netanyahu denied that the Israeli military were being heavy-handed in their search for the youths.
