Tel Aviv, Israel (AP) — Israel deported two activists on Sunday after being detained for slightly over a week for leading an aid flotilla attempting to break the Israeli naval blockade of the Gaza Strip.

The two, Spanish-Swedish citizen of Palestinian origin Saif Abukeshek and Brazilian citizen Thiago Ávila, were among dozens of activists intercepted by the Israeli navy off the coast of Crete. Both are members of the Global Sumud Flotilla’s steering committee, whose mission is to break Israel’s naval blockade and bring some humanitarian aid to the Palestinian territory.

The Israeli Foreign Ministry called the two activists in a post on X on Sunday “professional provocateurs,” saying ”Israel will not allow any breach of the lawful naval blockade on Gaza.”

At the time of the arrest, Israeli authorities said the two had been detained for questioning, and that Abukeshek was “suspected of affiliation with a terrorist organization” and Ávila was “suspected of illegal activity,” without providing evidence. No formal charges have been publicized against the two, the last activists who were held in Israel.

Spain and Brazil have condemned“the kidnapping of two of their citizens in international waters by the Government of Israel” in a joint statement at the time. The two activists’ detention sparked solidarity protests in several countries.

After arriving in Athens, Abukeshek insisted that he would continue protesting Israel’s blockade of Gaza and what he said was the mistreatment of Palestinian prisoners in Israel.

“We have to continue mobilizing. We can’t forget the Palestinian prisoners,” he said in a video comment posted on the Global Sumud Flotilla’s X account.

In all, 22 boats and 175 activists were intercepted by the Israeli navy. Activists said Israeli forces stormed their vessels, smashed engines and detained some of those onboard. The incident occurred hundreds of miles (kilometers) from Gaza and Israel overnight from Wednesday to Thursday.

Israeli officials said they needed to take early action against the flotilla before it reached Israeli waters because of the high number of boats involved.

The flotilla’s latest attempt to reach Gaza comes less than a year after Israeli authorities foiled a previous effort by the group. That attempt involved about 50 vessels and around 500 activists, including Swedish climate activist Greta Thunberg, Nelson Mandela’s grandson Mandla Mandela, and several lawmakers.

Israel arrested, detained and later deported the participants, including Ávila, who claimed Israeli authorities abused them while in detention. Israeli authorities denied the accusations.
