Israeli Arab reported knifing policeman near Allah-Las concert venue

A 24-year old man, described as an Israeli Arab, Thursday attacked with a knife Polish police outside the Warsaw concert hall where the Allah-Las band was about to perform.  In the struggle to detain him, a policeman was stabbed in the face. Police later denied witnesses’ report that the assailant also carried a gun. The night before, Rotterdam authorities cancelled an Allah-Las performance after receiving a Spanish police tip-off of a terror attack.
