Geopolitical tensions have spilled over into the Venice Biennale contemporary art exhibition. The event opens Saturday with no Golden Lions after the jury quit in protest of Israel’s and Russia’s participation. Protests erupted outside their pavilions. The jury limited its action to countries under investigation by the International Criminal Court. Visitors will vote for the best national pavilion and participant in the main show, “In Minor Keys.” Winners will be announced November 22. Ahead of the opening, protesters objecting to Israel's participation clashed with police. Earlier in the week, feminist groups from Ukraine and Russia converged on the Russian Pavilion.
