Tooting terror suspect Syed Talha Ahsan lost his fight against extradition to America on Monday, but his family have vowed to appeal the decision.

The 28-year-old former Franciscan Primary School pupil faces extradition to Connecticut, where he has been charged with running websites that support terrorism, in a case connected to fellow Tooting suspect Babar Ahmad, 32.

Judge Nicholas Evens ruled there were no human rights issues blocking Ahsan's extradition, meaning there is likely to be little objection from Home Secretary John Reid, who must make the final decision.

However the suspect's father, 68-year-old Syed Abu Ahsan, told reporters he remained confident in the British justice system and said his son should be tried in the UK.

Ahsan, a student who lived with his family in Franciscan Road, has been held without charge since July last year.

The American authorities believe he is connected to Azzamm Publications, a Tooting-based organisation allegedly headed by Babar Ahmad, that ran a number of websites recruiting and fundraising for the Taliban and Chechen Mujahideen from 1998 to at least 2002.

US prosecutors also claim Ahsan harboured terrorists in London, helping to organise their travel arrangements, and allegedly possessed a classified US Navy document which detailed a battle group's movements and its vulnerability to attack.
