Police spokesperson said on Tuesday it will initiate an investigation against the family of terrorist Ahmad Mahameed over violations of the restrictions imposed on his funeral.

Mahameed attempted to stab a policeman in the Jerusalem Old City last week and was shot by police forces.

Defense Minister Avigdor Liberman tweeted in response to the event: "Are you asking yourself why Umm el-Fahm should be part of Palestine and not Israel? The sights from last night of hundreds of people participating in the funeral of a terrorist from their town with the flags of Palestine, and the cries, "In spirit and blood we shall avenge the Shahid", should finally answer your question.

"The plan I published many years ago for the exchange of territories and populations is more relevant than ever," says Liberman.
