Amnesty activists held at U2 gig
Five Amnesty International activists have been arrested in Moscow for handing out leaflets to the audience before a U2 concert.
Concert-goers were being asked to sign petitions urging Russian authorities to bring the killers of journalist Anna Politkovskaya and human rights activist Natalya Estemirova to justice.
The activists, who were released after a few hours, were detained because they were not authorised to distribute the leaflets, according to a police spokeswoman.
The head of Amnesty's Moscow office, Sergei Nikitin, said U2's management had assured them before Wednesday's show that all the necessary permits were in place.
Russian police routinely break up protests.
