MORE than two dozen young wanna-be jihadis have made plans to leave Brighton and fight in Syria for ISIS or other terrorist groups, a new review is expected to reveal.

Counter-terrorism officials believe up to 28 city youngsters, including five teenage girls who had converted to Islam, were preparing to become involved in terrorist groups.

The new council-led review also raised concerns that members of the group could carry out terrorist attacks in Brighton and Hove using knives or guns.

Authorities have used court orders on three of the city’s aspiring terrorists, including one girl, to stop them leaving the country while five others, including three brothers from the Deghayes family, managed to reach Syria and join an al-Qaeda affiliated group.

The Sunday Times reports today that an unpublished assessment by counterterrorism and council officials in March 2014 revealed concerns that members of the group would seek to carry out a similar attack to the one which saw Lee Rigby stabbed to death on the streets of London in May 2013.

An attack using pistols was also considered possible but a bomb attack considered unlikely because the group would not be able to get hold of explosives.

A source told the national newspaper that the concern has “not abated” and that extremism linked problems remained in the city.

A redacted version of the report is to be released soon and is expected to also revealed that police and social services missed a number of chances over the past five years to counter the radicalisation of the Deghayes brothers.
