Israeli authorities have said they are taking two activists who led an aid flotilla bound for Gaza — and were captured by Israel in international waters of the Mediterranean Sea — to Israel for questioning.

The activists, Palestinian-Spanish citizen Saif Abukeshek and Brazilian citizen Thiago Avila, were among dozens of activists intercepted by the Israeli navy off the coast of Crete.

They are members the Global Sumud Flotilla's steering committee, whose mission was to break Israel's naval blockade and bring some humanitarian aid to the Palestinian territory.

In all, some 20 boats and 175 activists were intercepted by the Israeli navy.
