Pro-Palestine student activists at the University of Sydney have confirmed they’re closing down their encampment after a two-month siege on the uni’s lawns, amid revelations of Islamic extremists in their midst.

The Students for Palestine group said the decision to end the protest came after ­university management took a “consistently hostile approach” to the encampment.

Last Friday, the university told encampment representatives to vacate the site and authorised security to begin removing tents. Organisers have now relented, instructing ­protesters to retrieve their belongings “this week”.

However, Jewish leaders say the University of Sydney had not done nearly enough to deter the protest, particularly after it was revealed over the weekend that Muslim extremist group Hizb ut-Tahrir had ­allegedly infiltrated the uni ­encampment.

In a letter sent to Vice-Chancellor Mark Scott, the Zionist Federation of Australia and Australasian Union of Jewish Students accused him of negotiating with extremists, creating “a direct threat to the safety” of all students at the university.

“This was a terrible mistake,” the letter said.

A spokeswoman for the university said police had assured university management they would be informed of any “extremist, violent or radicalised behaviour” related to the camp and “no concerns have been raised … by police or other government intelligence agencies”.

In a letter to staff and students yesterday, Mr Scott confirmed management had sought advice from authorities on the allegations of Hizb ut-Tahrir’s involvement in the encampment.

Last night, a renewed protest kicked off after a coalition of Muslim clubs broke away from student council-aligned activists, with a controversial group alleged to have extremist links at the helm. Stand4PalestineAus issued the rallying cry for an ‘Eid March’ attended by about 40 people at the camp.
