The International Solidarity Movement and its deluded foot soldiers are still causing trouble, supporting the wrong side in a battle they don’t understand: Pro-Palestinian Brit refuses to leave.

A British citizen and member of the pro-Palestinian International Solidarity Movement, arrested a month ago after allegedly assaulting a soldier in Hebron, cannot be deported from Israel despite being considered a security risk, The Jerusalem Post has learned.

Andrew Macdonald, a 31-year-old Glasgow native, has spent the past three weeks in a detention center in the south awaiting deportation. Police confirmed on Wednesday that they were unable to deport Macdonald due to his refusal to board a Scotland-bound plane and his alleged threats to disrupt the flight.

Macdonald, who is currently being held in the Immigration Police Tzohar Detention Center, was arrested on November 3 with two other ISM activists after allegedly assaulting a group of soldiers standing at an IDF roadblock in the Tel Rumeida neighborhood in Hebron.

Macdonald was eventually released but was arrested again in Hebron on November 24 after he was caught in the West Bank city with an expired visa. Three weeks ago, police escorted Macdonald to an airplane at Ben Gurion Airport but he refused to board and according to police threatened to disrupt the flight.

Speaking to The Post from his prison cell, Macdonald rejected accusations that he made threats prior to boarding the plane and claimed to being repeatedly harassed by the prison commander. He further dismissed police claims he was a “provocateur” and said that he came to Israel to fight the occupation of the Palestinian people.

“I was involved in anti-occupation activity,” Macdonald said. “There was no anti-Israel activity.”

But the Shin Bet (Israel Security Agency) claimed that Macdonald was a security risk. Two years ago, he was deported after soldiers arrested him while holed up in a suicide terrorist’s family’s home they were trying to demolish. He was expelled from the country and his name was added to the Shin Bet’s watch list. In August however, Macdonald succeeded in entering the country again after he legally changed his name.
