TEL AVIV — A student was killed and at least 18 others injured after explosions went off at two bus stops in Jerusalem at the height of the morning rush hour, in what Israeli security forces are treating as a “combined terror attack.”The first explosion occurred at about 7:05 a.m. local time, near a bus station located at the exit from the city.The first blast killed Aryeh Schupak, a 15-year-old Canadian Israeli yeshiva student who lived in the Har Nof neighborhood of Jerusalem.He said in a tweet that he was “appalled by the cowardly terrorist attacks in Jerusalem today that targeted innocent civilians, including children.”Israel’s emergency services, known as Magen David Adom, said that four of the injured were in serious condition.More than 5,000 Israeli security officers were deployed throughout Jerusalem in the wake of the blasts, some searching other bus stops for any additional planted explosives.Prime Minister-elect Benjamin Netanyahu, who is in the midst of coalition negotiations to form the most right-wing government in Israel’s history, tweeted on Wednesday morning that he was “praying for the peace of the injured in the combined terror attack in Jerusalem this morning and backing the security forces operating in the field.”Netanyahu called for the swift formation of the new government to “return security to the citizens of Israel.”Itamar Ben Gvir, a far-right politician who is set to be appointed as Israel’s public security minister, tweeted that the bombing “takes us back to the difficult intifada period.”He vowed a return to the policies of targeted assassinations of Palestinian leaders, curfews on the hometowns of assailants, lockdowns in prisons with Palestinian inmates, and stopping Palestinian authorities from paying compensation to those who served time in Israeli prisons or were harmed in clashes."
