All but two pro-Palestinian activists detained by Israeli forces after their flotilla headed for Gaza was intercepted in international waters have now been released in Greece.

On Thursday, around 175 activists aboard 22 boats carrying aid were seized near the island of Crete.

The organisers of the Global Sumud Flotilla (GSF) denounced the action as "piracy", saying members were seized unlawfully more than 965km (600 miles) from Gaza, which is under an Israeli naval blockade. Israel's foreign ministry called the flotilla a "PR stunt".

All the detained activists have disembarked in Crete, apart from two men who are being brought to Israel "for questioning", according to the Israeli government.

Israel's foreign ministry said that one of the men, Saif Abu Keshek, was "suspected of affiliation with a terrorist organisation" and the other, Thiago Ávila, was "suspected of illegal activity". Both men remain in Israeli custody.
