Go tell it to the marines, literally — one of the Gaza flotilla activists claimed he was taking a fishing trip and had no intention of breaking the blockade.

The two detained activists, Spanish national Saif Abu Keshek and Brazilian Thiago Avila, attended a second hearing Tuesday after they were brought to Israel for further questioning. Police had requested a five-day extension of the activists’ custody, and the court approved the request, extending their detention until Sunday.

Hebrew media reported that Avila’s lawyer said he had embarked on an innocent fishing trip to Greece and hadn’t intended to sail to Gaza to break the blockade. Unfortunately for Avila, he’s a known anti-Israel activist who has been filmed leading a chant of “Death to America! Death to Israel! Victory for Islam!” It’s going to be hard for him to pull off this story.

The flotilla of 58 boats and 170 activists had departed from France, Spain and Italy for the express purpose of attempting to break Israel’s blockade of Gaza. The Israeli navy intercepted the flotilla last week and deported all but two of the activists to Greece, retaining Keshek and Avila for questioning.

Israel has accused the pair of ties to the Popular Conference for Palestinians Abroad (PCPA), an organization that acts on behalf of Hamas. Israel’s Foreign Ministry said that Keshek was an actual leader of the group, while Avila was linked to the group and was “suspected of illegal activity.”

The Israeli rights group Adalah said the activists had embarked on a hunger strike, with Tuesday marking their sixth day of refusing nourishment. The rights group also alleged that the prisoners were subjected to abuse: held in isolation, subjected to continuous “high-intensity” lighting and cold temperatures, and blindfolded at all times.

Israeli authorities denied the allegations.
