TEHRAN -- The UK government has put in place measures to freeze the funds of 34 groups, including the Mojahedin Khalq Organization (MKO), suspected of involvement in financing of terrorism, Treasury Minister Ruth Kelly has confirmed.

"The government are committed to the fight against terrorism and since the events of September 11 have led by example in issuing asset freeze lists against individuals and organizations," Kelly told Parliament on Monday in London.

UN Resolution 1373, issued on September 28 last year, calls on states to freeze the funds and financial assets of persons or entities involved in terrorism, IRNA reported.

The treasury minister said that the UK was implementing the resolution against its list, which included the MKO, where there were reasonable grounds to suspect that an organization is involved in the financing of terrorism.

"The government will not hesitate to meet their international obligations by freezing their assets," she said.

Last December, Britain's charity commission reported that after a two year investigation it was unable to trace some PNDs 5 million ($8 m) a year of funds collected by Iran aid, a charity suspected of links with the MKO terrorist group.

The investigation came after Iran aid was dissolved following a two year siege of its offices, that were illegally occupied in north London.

The MKO, which has carried out frequent terrorist attacks in Iran for two decades from its base in Iraq, was proscribed by the UK as a terrorist group early last year.
