Greta Thunberg detained: What really happened on the Gaza Flotilla?

Climate activist Greta Thunberg was among hundreds of international volunteers detained when Israeli naval forces intercepted the Global Sumud Flotilla, a convoy of boats attempting to break the blockade of Gaza. The flotilla, one of the largest aid missions in years, had set sail with more than 40 vessels carrying symbolic humanitarian supplies and nearly 500 activists from around the world.

The interception, which took place in international waters about 130km off Gaza’s coast, has triggered an international outcry, with governments and human rights groups accusing Israel of violating maritime law.

What Happened During the Interception?

According to flotilla organisers, Israeli naval ships cut communications before boarding at least 13 vessels late on Wednesday. Reports say more than 201 activists from 37 countries were detained, including nine Irish citizens, 65 Spaniards, and others from Italy, Turkiye, Malaysia, and the United States.

Footage released by Israel’s Foreign Ministry showed Greta Thunberg sitting calmly on deck, surrounded by soldiers, before the ships were diverted to an Israeli port. Activists claimed their communications were deliberately jammed to prevent distress calls or live streaming of the raid.

Why Did Israel Stop the Flotilla?

Israel’s navy insisted the flotilla attempted to “breach a lawful naval blockade” imposed on Gaza since 2007. Officials argued that any humanitarian aid must be delivered through established channels under Israeli control.

Critics counter that the blockade violates international law by preventing food, medicine, and essential goods from reaching Gaza’s population. Organisers of the flotilla stressed their mission was peaceful, symbolic, and aimed at opening a humanitarian maritime corridor.

Why Was Greta Thunberg on Board?

Greta Thunberg, known globally for her climate strikes, has increasingly tied environmental justice to human rights struggles. By joining the flotilla, she aimed to draw attention to Gaza’s humanitarian catastrophe, where nearly two years of war have left families facing famine, displacement, and limited access to aid.

Her presence has amplified global attention on the flotilla, making headlines across Europe and beyond.

International Reaction to Israel’s Actions

The interception sparked swift diplomatic fallout:

• Ireland’s Foreign Minister Simon Harris called the flotilla a “peaceful mission to shine a light on a horrific humanitarian catastrophe” and demanded detained citizens be treated properly.
• Spain summoned Israel’s top envoy after 65 of its nationals were arrested.
• Malaysia’s Prime Minister Anwar Ibrahim condemned Israel’s “intimidation and coercion.”
• Colombia expelled Israeli diplomats and suspended a free trade agreement in protest.
• Turkiye and Venezuela described Israel’s actions as violations of international law and “acts of war.”

Meanwhile, pro-Palestinian protests erupted in cities including Rome, Buenos Aires, and Istanbul.

A History of Flotilla Confrontations

This is not the first time activists have tried to break the blockade:

• 2010: The Mavi Marmara raid left 10 activists dead when Israeli commandos stormed the Turkish vessel.
• 2011–2018: Smaller flotillas were stopped, with activists detained, beaten, or deported.
• 2024–2025: Renewed attempts, including June 2025’s Madleen mission, saw Israel intercept ships in international waters.

The Sumud Flotilla of 2025, however, stands out as one of the largest efforts since 2010.

What Happens Next?

Israel has confirmed that detained activists, including Greta Thunberg, will be processed and deported to Europe once the Yom Kippur holiday ends. Until then, many remain in legal limbo as Israeli courts and prisons are closed.

For Gaza, the flotilla’s interception highlights the continuing struggle to deliver humanitarian aid by sea. For the global community, it has reopened debates about the legality of Israel’s blockade, the limits of peaceful activism, and the risks faced by those who challenge restrictions in one of the world’s most contentious conflicts.
