The father of a British teenager killed in Syria has said he is "scared" for his two other sons and urged them to leave the war-torn country where they have gone to fight.
Abdullah Deghayes, 18, from Brighton, is believed to have died in Kassab, in Latakia province, earlier this month after leaving the UK in January.
Abubaker Deghayes, who learned of his son's death on Monday via Facebook, said his two others sons, Jaffar, 16, and 20-year-old Amer have also travelled to Syria and pleaded for them to return.
He told The Guardian: "Amer, Jaffar, if you see me or this interview please, please come back home. Enough. This war has taken Abdullah already... I'd like to see you live longer."
Mr Deghayes revealed he travelled to Turkey earlier this year to meet Abdullah and Jaffar in an attempt to stop them entering Syria to fight.
He said Amer had already travelled there in December, and told him he had joined the jihadist group Jabhat al-Nusra.
"I am scared for my children," he told the paper. "I don't want to lose them obviously. But they are becoming men now."
Speaking outside his home in Brighton on Friday, Mr Deghayes said his son had died a martyr in a battle which also saw Amer suffer a bullet wound to his stomach.
"I am sad for the loss of Abdullah but at the same time I can feel some comfort that he went for a just cause," he said. "The cause is to help those who are being bombed daily by Assad and killed by his bombings and air raids and soldiers for nothing except to ask for their freedom.
"I hope this was his intention, I hope he is rewarded and I hope he is in peace now."
Mr Deghayes insisted his three sons were not "terrorists" but had travelled to Syria to defend "those who are weak".
Abdullah, who was due to go to university in Brighton, is the nephew of Omar Deghayes, who was held by the United States as an enemy combatant at Guantanamo Bay detention camp between 2002 and 2007 after he was arrested in Pakistan.
