Paris has deployed hundreds of extra police to protect an urban beach event honoring Tel Aviv, after it turned from a summertime celebration into a geopolitical hot potato.

Leftist politicians and pro-Palestinian activists wanted it canceled amid anger over a Jewish extremist attack in the West Bank. But Paris city hall stood firm.

City authorities said extra police will protect the one-day event Thursday on the banks of the Seine River. It's part of a larger summer event called Paris Plages that transforms quayside city streets into beaches.

Protesters plan a rival "Gaza Plage" event Thursday near Notre Dame Cathedral.

Paris remains on alert after Islamic extremist attacks in January. Unrest in the Mideast sometimes translates into tensions in France, home to large Muslim and Jewish populations.
