The Liberty Fleet Alliance plans to conduct a second regatta program after an earlier attempt, the target of a drone attack targeting Israel.

Swedish climate activist Greta Thunberg and Game of Thrones actor Liam Cunningham will join the next voyage of the Free Flotila Alliance (FFC) in an attempt to break Israel's months-long Gaza lockdown.

"Madleen" will be discharged from Catania, Sicily on Sunday, and cargo of humanitarian aid and several high-profile activists on board, including Thunberg, including European Parliament Rima Hassan and Palestinian-American attorney Huwaida Arraf.

Cunningham is an Irish actor known for his role as Davos Seaworth in the HBO series, a longtime advocate for Palestine and similar causes.

Sailing marks the second attempt by the FFC, a coalition of humanitarian groups, to reach Gaza in months.

A mission in early May was suspended after another FFC ship, "Conscience", and while sailing in international waters along the coast of Malta, two drones allegedly attacked two drones.

The FFC claims Israel is responsible for the attack, which severely damaged the front of the ship.

MEP Hassan said in a short video on social media that the trip to “Madleen” was a protest against Israel, like trying to provide much-needed aid to Gaza.

"The first (target) is of course a rejection of humanitarian aid blockade, ongoing genocide, impunity enjoyed by the State of Israel and raising global international awareness," she said.

"This operation is also a response to the May 2 attack on a ship on international waters near Malta."

Last week, Israel partially lifted its nearly three-month lockdown on Gaza, but has since provided only a small amount of aid to the Palestinian territory, with the United States warning that it is the brink of famine.

This week, thousands of Palestinians rushed to the so-called aid distribution station established by the controversial Gaza Humanitarian Foundation, killing at least three people and causing dozens of injuries amid the chaos, which was chaotic as desperate people tried to get food supplies.

The United Nations and other humanitarian groups are boycotting U.S. and Israel-backed initiatives, accusing Israel of trying to consolidate and control the distribution of aid across Gaza to further arm food and hunger.

The World Health Organization warns that Gaza is at risk of famine after a long-term food shortage in Israel’s punitive lockdown, with about a quarter of its population in “catastrophic situations of hunger, acute malnutrition, hunger, hunger, disease and death.”
