Budapest  - Right-wing extremists hurled stones and eggs at a Gay Pride procession in the Hungarian capital on Saturday before clashing with police called in to protect the marchers.

Police arrested more than 40 of the assailants, who threw firebombs at the officers and set alight a police minibus. At least five persons were injured, two of them policemen.

A jazz concert due to be held at the end of the rally was cancelled for security reasons.

Politician Gabor Horn, a leading member of the liberal Association of Free Democrats (SZDSZ), said he was spat upon, slapped and doused with beer by neo-Nazis.

It was the worst violence during the 12 years the Gay Pride parade has taken place in Budapest.

Hundreds of of extremists gathered along the route taken by the 1,500 marchers to give vent to their anger at gays and lesbians.

In the days leading up to the parade, calls were made on Neo-Nazi internet forums for violence to be used against the "unnatural perverts." (dpa)
