International Criminal Court judges have called on the court's prosecutor to reconsider her decision not to investigate the storming by Israel of an aid flotilla that was heading to Gaza.

Prosecutor Fatou Bensouda last year declined a request by the Union Comoros to launch a probe into the May 31, 2010, storming of one of the flotilla vessels, which was sailing under a Comoros flag.

Bensouda said there was a "reasonable basis to believe that war crimes" were committed on the Mavi Marmara, where eight Turks and one Turkish-American were killed and several other pro-Palestinian activists wounded by Israeli commandos, but that the case wasn't serious enough to merit an ICC case.

Judges ruled Thursday that Bensouda made "material errors in her determination of the gravity" of the case.
