A group of ultra-nationalists affiliated with Alperen Hearths, an offshoot of the Turkish nationalist movement called the Grey Wolves (Ülkü Ocakları), gathered in front of the Neve Shalom synagogue in Istanbul on Thursday night and kicked the synagogue’s gates while throwing stones in protest of Israel’s security measures at Temple Mount.

Israeli government installed some metal detectors at the holly compound after assailants killed two Israeli police officers last weekend. The Muslim religious body that has authority over the site announced that the metal detectors are an attempt to change the status quo and called on worshipers not to enter the site. Since then, violent clashes between ISraeli soldiers and Muslim protestors have been going on at the compound.

The nationalist group said in a statement read outside the Neve Salom synagogue that Israel was a “terror state” seeking to block freedom for worship to Muslims.

“If you prevent our freedom of worship there then we will prevent your freedom of worship here,” said the statement, read by the group’s local chairman Kursat Mican.
