Latin American anger grows over Israel’s detention of Thiago Ávila

Anger is spreading across parts of Latin America after Israeli forces intercepted the Global Sumud Flotilla in international waters and detained activists, including Brazilian citizen Thiago Ávila. The case has triggered diplomatic pressure from Brazil, criticism from civil-society groups, and sharper legal and political reactions from Chilean and Palestinian community figures in the region. The outrage has intensified further after reports circulated this morning claiming that Thiago’s mother had died from grief over her son, who remains detained in Israeli prisons.

In Brazil, public pressure has moved beyond official statements. Around 20 protesters gathered on Tuesday morning in São Paulo to demand Ávila’s release after he was detained by Israeli forces during a humanitarian mission in the Middle East. The activists delivered a document to be forwarded to the Ministry of Foreign Affairs in Brasília, calling not only for his immediate release but also for Brazil to sever relations with Israel.

Brazil has taken the lead in condemning Ávila’s detention.

President Luiz Inácio Lula da Silva demanded the immediate release of the Brazilian activist, calling his continued imprisonment “an unjustifiable action by the government of Israel.”

Lula said the detention caused serious concern and “must be condemned by all.”

The Brazilian president also linked Ávila’s case to the broader interception of the flotilla, arguing that the detention of activists in international waters represented a serious affront to international law. Brazil’s position is not limited to consular concern; it has become a diplomatic demand. Lula said his government, together with Spain, which also had a citizen detained, requires full guarantees for the activists’ safety and their immediate release.

The reaction in Latin America has not been uniform, but the political temperature is rising. Inside Brazil, the case has also mobilized pro-Palestinian activists and civil-society groups. Demonstrators and solidarity networks have pressured the Brazilian Foreign Ministry to take concrete action, arguing that Ávila’s detention is not an isolated consular incident but part of a broader campaign against humanitarian activism directed toward Gaza. 

Colombia has aligned with Brazil in condemning the interception of the flotilla and demanding the release of detained activists.

In Chile, criticism has been especially sharp from Nelson Hadad, a former Chilean ambassador to several Arab countries and the legal representative of the Global Sumud Flotilla initiative in Chile.

Hadad said the Israeli interception of the flotilla in international waters amounts to a direct breach of international law.

“What happened can be legally characterized as an illegal interception, a crime of kidnapping and forced detention, and, according to some legal classifications, may amount to an act of piracy, especially since it targeted civilians who were participating in a humanitarian mission.”, Hadad told MEMO.

He described the operation as a clear legal violation, saying that the nature of the attack and its location in international waters required a much firmer response from Chile. Hadad said he had informed Chile’s deputy foreign minister that the incident involved “a clear violation of the Convention on the Law of the Sea,” and argued that the government should have adopted a stronger position.

Hadad also confirmed that legal action is being considered against Israeli Prime Minister Benjamin Netanyahu. According to him, a team of lawyers is preparing to study an international criminal complaint against Netanyahu over alleged war crimes, crimes against humanity, and genocide. He said the complaint would be based partly on the Convention on the Prevention and Punishment of the Crime of Genocide.

The former ambassador was particularly direct on the humanitarian dimension. He argued that “using starvation as a method of warfare” can constitute an element of genocide. He said that depriving civilians in Gaza, especially children, of food, water, and essential supplies reflects a deliberate attempt to deny them the basic conditions necessary for survival.

Hadad also criticized Chile’s Foreign Ministry for what he considered a weak official response. He said he felt “great disappointment” that the ministry merely expressed “concern” instead of issuing a clear condemnation. In his view, the Chilean position was “weak and soft,” and such language does not create real political or legal pressure. Instead, he argued, it leaves room for Israel to continue committing violations without accountability.

The Palestinian community in Chile also criticized the government’s handling of the case. In a statement, the community expressed “deep concern, condemnation, and disappointment” over the authorities’ limited response to the detention of Chilean citizen Macarena Chahuá, the Brazilian Thiago Avila and other activists. It described their detention in international waters as an “illegal and arbitrary kidnapping” and a blatant violation of international law.

The community said the Chilean government’s reaction was insufficient and failed to match the seriousness of the incident. It demanded a clear official position, including explicit condemnation and a direct call for immediate and unconditional release, rather than relying only on diplomatic procedures and consular follow-up.

The message from Chile’s Palestinian community was direct: Chile’s foreign policy has historically been built on respect for international law and human rights, and that legacy should not be weakened when Chilean citizens are detained in what the community sees as an illegal operation. The community closed by calling on the government to correct its position, raise the level of its response, and act “with clarity, consistency, and firmness,” stressing that “defending our citizens cannot tolerate ambiguity.”

Taken together, the reactions from Brazil, Colombia, Chilean legal figures, and Palestinian communities in Latin America show that the detention of Thiago Ávila has become more than a Brazilian consular case. It is now part of a wider regional dispute over Israel’s conduct, international law, and the limits of diplomatic language.
