Photographs of two teenagers who flew to Turkey in a bid to join ISIS were revealed last night, as a Muslim leader warned they could be followed by friends. Farouk Younis, the imam of the mosque used by relatives of Hassan Munshi and Talha Asmal, said Muslims must talk to other teenagers who ‘might be looking at them and thinking this is the way’. The 17-year-olds from Dewsbury, West Yorkshire - billed by their families as two ‘ordinary Yorkshire lads’ - are believed to have travelled to war-torn Syria after going to Turkey on Tuesday last week.

The next-door neighbours are close friends and were seen playing snooker at Dewsbury Snooker Centre about a week ago, acquaintances told the newspaper. Earlier this week, police said the boys from Dewsbury were last seen by their families on the day they are believed to have flown from Manchester to Dalaman.

A statement released on behalf of the two families on Tuesday said they are devastated at what has happened. It said: ‘Our number one priority is to get Hassan and Talha back home with their families and we implore anyone who may have any information whatsoever to get in contact with the police. ‘Naturally, we are in a state of profound shock and are trying to come to terms with the predicament we find ourselves in and we hope and pray that no other family finds itself in our situation. ‘These were just two ordinary Yorkshire lads who enjoyed the things that all young people enjoy at their age. ‘Both Hassan and Talha had a promising future, as an apprentice and an A-level student respectively, and we are praying they will be back with us soon and are able to realise that future.’ The families have urged parents to be extra vigilant, saying it is ‘near impossible’ to know if children have been groomed and brainwashed. Hassan is believed to be related to Hammaad Munshi, who was arrested by counter-terrorism police in 2006 at the age of 15 and later convicted over his role in a plot to murder non-Muslims, reported The Times. The Metropolitan Police believe around 600 Britons have travelled to Syria and Iraq since the conflict began, while around half are believed to have returned to the UK. Nine Britons - including the son of a Labour councillor - were arrested in Turkey last week on suspicion of trying to cross the border into the neighbouring country.
