Moscow, Dec 22 (IANS/RIA Novosti): Belgian police have arrested four activists of Ukraine's Femen movement when they attempted to hold a topless protest in Brussels where the Russia-EU summit is underway.

The EUbusiness news portal said that shortly after Russian President Vladimir Putin arrived at the EU headquarters for talks with EU president Herman Van Rompuy and European Commission head Jose Manuel Barroso, four Femen activists began walking towards the EU building.

The women, who were stripped to the waist and painted with protest messages, shouted anti-Putin slogans.

"The 'Putin Is the Apocalypse' protest lasted only minutes," the portal said.

The women were "thrown to the ground by a dozen burly police" and hauled off in a police van. The protest caused no disruption to the summit.

Ukraine's radical feminist movement Femen was established in 2008 and was devoted mainly to protests on women's issues. Later the group made headlines for pro-democracy and anti-corruption protests in Russia, Ukraine and London.
