The father of a British man who has appeared in a video aimed at recruiting jihadists has said he is “heartbroken” his son left the UK to fight in Syria.
In the film, would-be medical student Nasser Muthana, 20, from Cardiff, urges others to fight in Syria and Iraq.
His father, Ahmed Muthana, told the BBC his younger son had also gone to Syria.
The BBC understands two men who travelled with Nasser were held on suspicion of terror-related offences on their return to the UK but not charged.
South Wales Police said the men, aged 19 and 23 and from Cardiff, were arrested earlier this year on suspicion of receiving terrorist training and attending a place used for terrorist training in Syria.
Father’s ‘coffin’ fear
Mr Muthana – whose son Nasser appears in the footage using the name Abu Muthanna al-Yemen – told BBC Wales his 17-year-old younger son, Aseel, had also travelled to the country.
He said another man in the video, which cannot be verified, was someone he recognised from Cardiff.
The footage emerged after militants led by jihadist group the Islamic State in Iraq and the Levant (Isis) made rapid advances through Iraq in recent weeks, seizing several northern cities and surrounding the country’s biggest refinery.
Mr Muthana told the BBC he feared his sons would “come back to me in a coffin”.
