UK Syria fighters: Anti-terror police 'doing their best'

The head of Wales' counter-terrorism unit has denied that police are failing in their efforts to combat the radicalisation of young Muslims.

It comes after a video showed two young Cardiff men urging others to join a jihadist fight in Syria and Iraq.

The father of one of them - Nasser Muthana - claimed police had failed to win the trust of Welsh Muslims.

South Wales Assistant Chief Constable Nikki Holland said police could not "keep a hold of everybody" and could only tackle extremism with community help.

She also told the BBC's Hywel Griffith that the force's anti-radicalisation scheme Prevent could be working with children in primary schools in future.
