Left-wing extremists defaced three monuments to Israeli terror victims and fallen members of the security services in the Jordan Valley, police discovered on Thursday, just one week before Israel honors its war dead.

Anti-Israel slogans in Hebrew were found spray painted in black on the memorials, including the words “the fallen were killed for their treason” on a stone wall bearing the names of hundreds of soldiers that were killed since 1967.

The vandals drew a Palestinian flag on the monuments as well.

Police were first alerted to the attack by the mother of Salit Sheetrit, who was murdered in a shooting terror attack near the Mehola settlement in 2001. A memorial named after Sheetrit was one of those defaced.

“Forensic teams are on the site, gathering evidence,” Judea and Samaria Police spokeswoman Nurit Tzemah told The Jerusalem Post.

Vandals also targeted a third memorial set up to honor two traffic policemen shot dead by terrorists on Route 90.

Police inspected other memorials in the West Bank and found that they had been left untouched.

“All possible directions are being considered,” Tzemah said.

“What we’re talking about here is nothing less than a terrorist attack,” said David Elchiani, the head of the Jordan Valley Regional Council.
