- Six Portmouth men radicalised online ended up going to Syria to fight
- Five of them were killed while battling with ISIS and another was jailed
- Now 30 mothers from the city have been given training in warning signs
Muslim mothers in families close to British jihadis who went to Syria are being trained to spot the signs their children are being groomed by extremists.
Six young men from Portsmouth went to fight for ISIS after being radicalised online, with five having since been killed and another jailed for terror offences.
Now 30 women in the Hampshire city, some of whom knew the jihadis' families, have been taught to check their sons or daughters don't follow a similar path.

Mehdi Hassan and Ifthekar Jaman also went from the Hampshire city to fight alongside extremists
Ifthekar Jaman, Assad Uzzaman, Mehdi Hassan, Manunur Roshid and Muhammad Hamidur Rahman were all killed in fighting while Mashudur Choudhur was jailed for four years in 2014.
All six men were radicalised after coming into contact with extremist preachers on social media.
A course of other mothers in Portsmouth, which organisers say is being undertaken predominantly by mothers of Muslim faith, was organised under the Prevent scheme, the government's counter-extremism programme.
Among the advice produced by the campaign is to keep an eye on children who switching screens when parents come near, lose interest in their friends or start believe conspiracy theories.
Charlie Pericleous, from Portsmouth City Council, said: 'This was a really successful course and the women learnt a lot about the need to keep children safe online, just as they would in the outside world.
'Children and young people spend a lot of time online, and although the internet can be a very positive tool, it's important parents are aware of the risks and how to safeguard their children.
'Some of the mums on the course knew the families of the young Portsmouth men who travelled to Syria a few years ago, with tragic results.
'The course increased their understanding of what material is on the internet, what made those young men become radicalised, and how we can all work together to stop it happening again.
