A Birmingham-based charity yesterday denied being a supporter of a militant Palestinian organisation after one of its workers was held for three weeks in a top-security jail in Israel.
Ayaz Ali, from Bradford, was working for Islamic Relief Worldwide in Gaza when he was arrested on May 9.
Israeli police say he was detained on suspicion of aiding the militant group Hamas, which they class as a terrorist organisation. Security forces say they suspected Islamic Relief Worldwide of supporting the organisation and of transferring funds to some of its various institutions.
But a judge ordered that 36-year-old Mr Ali, who was being held at the maximum-security Ashkelon Prison, be released without charge on Monday and deported back to the UK. He returned on Tuesday.
A statement issued by the charity vigorously denied any links to Hamas.
It said: "The allegations against Islamic Relief and Ayaz Ali are entirely unfounded and Islamic Relief will be making representations to the Israeli authorities refuting these claims.
"Islamic Relief does not transfer funds to any organisation in the Palestinian Territories.
"All its financial transactions are externally audited and also go through rigorous checks both internally and externally by the UK Charities Commission and agencies such as the European Commission who fund Islamic Relief's work in the Palestinian Territories."
Mr Ali has worked for the charity for five years and was appointed programme manager for its humanitarian projects in Gaza in December 2005.
He has also strenuously denied any links with the militant group.
"There is not a grain of truth in anything that Islamic Relief or I have been accused of by the Israeli authorities," he said on his return to the UK.
"I was interrogated for 20 days and every time I made it clear to them that we do not have any political links and are only interested in humanitarian work. In the end they found no evidence to support their claims and were forced to let me go."
