Anti-Christian Hebrew slogans have ruined the walls of a famous Jerusalem church, the Benedictine monastery.
Police spokeswoman Luba Samri said the slogans were found on the outer walls of the Dormition Abbey, where Christian traditionalists claim Virgin Mary died.
Nikodemus Schnabel, the Dormition Abbey spokesman, said the messages were "very radical,” some slogans included "Death to the Christians” and “Revenge for Israel.”
Police are investigating, with suspicion immediately falling on violent Jewish groups who have for years vandalised Palestinian property, mosques and churches.
The varying handwriting suggested a group took part in the violation.
Violent Jewish settlers have been engaged in "price tag" attacks on mosques and churches in the past.
Violent Israeli groups attacked Palestinians 399 times in 2013, resulting in many injuries and much property damage, according to a US report, cited by the UN Office for the Coordination of Humanitarian Affairs.
"The pricetag campaign included attacks by extremist Israeli settlers towards Palestinian villages, mosques and also churches," said the report.
Over the period from January 2012 to June 2013, Israeli police registered 788 cases of price tag assaults in which 276 were conducted, leading to 154 indictments, reported by Ynetnews.
The monastery, a popular site for tourists, has been damaged several times in recent years by the same groups who are believed to be involved in price tag attacks.
