The suspect was shot by prison guards driving by the scene as he jumped from the bus and tried to escape.
From Fox News:
Israeli Police spokesman Micky Rosenfeld posted a message on Twitter saying that authorities believe the incident is a terror attack. Eleven people were stabbed and three remain in critical condition, according to Lee Gat, a spokeswoman at Tel Hashomer hospital, and a statement from the Ichilov hospital.
Rosenfeld said the suspect is a 23-year-old man from Tulkarem, located in the West Bank northeast of Tel Aviv. He said the man was being questioned by police and a heightened security presence was in effect in Israel’s second-largest city. The Times of Israel reported that the suspect was shot in the leg as he attempted to flee the scene.
Tel Aviv District Police Chief Bentzi Sau said that members of the Israel Prison Service were in a vehicle behind the bus and noticed it driving erratically. Sau said officers then jumped out of their vehicle and pursued the suspect when they saw him get off the bus. He added that the suspect had crossed into Israel illegally, but did not specify how.
