Europeans Among Rebels Fighting in Syria
According to EU anti-terror official
The EU's anti-terror chief has told the BBC that hundreds of Europeans are now fighting with rebel forces in Syria against Bashar al-Assad's regime.
Gilles de Kerchove estimated the number in Syria at about 500.
Intelligence agencies are concerned some could join groups linked to al-Qaeda and later return to Europe to launch terrorist attacks.
The UK, Ireland and France are among the EU countries estimated to have the highest numbers of fighters in Syria.
