Hungary's Prime Minister has reportedly called for an anti-extremist rally to be held after far-right groups attacked marchers at Saturday's gay pride parade in Budapest.

According to media reports, 45 people were taken into custody and 10 others including two policemen were injured in clashes between dozens of protesters and riot police officers escorting the march through the centre of Budapest.

The protesters, many of them from ultra-nationalist groups, shouted out anti-gay epithets, and hurled eggs and cobblestones at parade participants; and gasoline bombs at the police.

A gay bar and a massage parlour were attacked with gasoline bombs in the week leading up to the parade although no one was injured and little damage was done to the buildings.

Following the clash, PM Ferenc Gyurcs�ny announced that a rally against extremists will be held on Sep 6.

News web site Politics.hu quoted the PM, who called the recent violent attacks the "final straw" as saying, "This is not a police, nor a gay, nor a Jewish, nor a Gypsy, but a common cause."

PM Gyurcs�ny further called on public dignitaries to "discuss why the majority of society appears to be weak in the face of extremists who terrorise the majority, and what is missing from the system of constitutional and democratic institutions."

Starting in January, all Hungarians involved in long-term relationships will be allowed to register their partnerships and enjoy some of the benefits of married couples, such as inheriting from each other. This will apply to heterosexual and same-sex couples.
