The UN Security Council has issued a statement calling for an impartial inquiry into Israel's raid on a flotilla of Gaza-bound aid ships.
The statement said the investigation should be "prompt, impartial, credible and transparent".
The statement was the result of a compromise between Turkey and the United States, with Turkey reluctant to water down its trenchant criticism of Israel while the United States, Israel's closest ally, wanted to temper the language used, says the BBC's UN correspondent Barbara Plett in New York.
Turkey is furious at the commando raid, which targeted a Turkish ship and appeared to have killed mostly Turkish activists, our correspondent says.
The compromise took out direct condemnation of Israel and removed references to an international investigation, our correspondent adds.
It also weakened demands for an end to the economic blockade of Gaza that the activists were trying to break, but the incident has refocused international attention on the siege and many states have renewed calls for it to be lifted, she says.
That means that almost 600 people, from several countries, are still being held in detention centres across Israel and are being questioned by the authorities.
Israel has imposed an information blackout, making it difficult to gather first-hand accounts from the campaigners.
