The Israeli navy on Wednesday stopped a boat carrying international female activists, preventing them from breaking the blockade of Gaza.

Among the 13 people on board the Women’s Boat to Gaza, a mission of the international Freedom Flotilla Coalition, were Nobel Peace Prize winner Mairead Maguire of Ireland, retired U.S. army colonel Ann Wright, New Zealand politician Marama Davidson, and Malaysian doctor Fauziah Hasan.

“In accordance with government directives and after exhausting all diplomatic channels, the Israeli navy redirected the vessel in order to prevent breach of the lawful maritime blockade,” the military said in a statement, according to Agence France-Presse.

“The visit and search of the vessel was uneventful,” it stated.

The Freedom Flotilla Coalition posted on its Facebook page that the boat was “attacked by Israeli Occupation Forces in International Waters.” The U.N. Convention on the Territorial Sea and Contiguous Zone states that territorial waters can extend out to 12 nautical miles.
