University students are being bombarded with leaflets promoting Muslim extremists who have called for homosexuals to be killed.

Student societies across London have distributed posters featuring organisations which have promoted extremist beliefs.

The freshers' fairs, hosted by student unions on university campuses in September and October, allow a range of societies to hand out promotional literature.

An event called the 'ILMFest' was advertised and the conference is being sponsored by Islamic studies institute, the AlMaghrib Institute, which was founded in Texas.

Student Rights has been reviewing the content handed out to students in recent freshers' fairs

The institute has been embroiled in a number of controversies after some of its students were later involved of terror plots.

Terror suspect Umar Farouk Abdulmutallab, who attempted to detonate explosives on a plane from Amsterdam to Detroit in 2009 took a class at the AlMaghrib Institute, according to CNN.

It also received public scrutiny for selling recordings of Anwar al-Awlaki, a cleric in Al-Qaeda, at their events. However, in 2009 the institute banned the recordings.

Next month's event will take place at the O2 Arena in London and speakers such as Omar Suleiman, Yasir Qadhi, Yayha Ibrahim, and Abu Eesa Niamutullah are all set to address the audience.

Student Rights has been reviewing the content handed out to students and their research manager is urging universities to do more to protect 'vulnerable' people from 'inappropriate material'.

One of the people due to speak at the event is Mr Suleiman, an Islamic preacher, who previously called homosexuality a 'disease' and a 'repugnant shameless sin'.

Meanwhile, Mr Qadhi said that to 'kill … the homosexual – this is also our religion', and that 'to make fun of Allah and his Messenger, the punishment is death'.

Richard Black, Research Manager of Student Rights, urged British universities to do more

Mr Ibrahim has said: 'Allah gives us almost an advice by warning us of who our enemies are… never will the Christians and the Jews be satisfied or content or pleased with you until you follow them and their religion'.

Mr Niamutullah added: 'The Ummah (Muslim community) 'is our primary identity' and that 'liberal people who call themselves Muslims are the biggest danger within our community at the moment'.

Richard Black, Research Manager of Student Rights, urged British universities to do more.

He said: 'Universities should make more rigorous checks to make sure extremist and inappropriate material does not target young and potentially vulnerable people'.

MailOnline has contacted the AlMaghrib Institute for comment.

Students Rights, a project of The Henry Jackson Society, describes itself as being a 'non-partisan group dedicated to supporting equality, democracy and freedom from extremism on university campuses'.
