At gay pride parades in Paris and other cities outside the US on Saturday, the US Supreme Court's ruling was hailed by many as a watershed.

"Soon in all countries we will be able to marry," said Celine Schlewitz, a 25-year-old nurse taking part in the Paris parade. "Finally a freedom for everyone."

Street celebrations were boosted Saturday in Dublin, where Ireland mounted the biggest gay rights parade in the country's history.

More than 60,000 people paraded at the culmination of a weeklong gay rights festival in the Irish capital. While the mood was already high following Ireland's referendum last month to legalize gay marriage _ becoming the first nation to do so by popular vote _ many marchers said the Supreme Court ruling provided a bonus reason to celebrate.

In Turkey, police used water cannons to clear a rally Sunday in Istanbul. Between 100 and 200 marchers were chased away from Taksim Square after a police vehicle fired several jets of water to disperse the crowd. It wasn't clear why the police intervened in the peaceful rally. The crowd regrouped a few blocks away.
