The Islamic State published on Thursday (June 18) a call for individual attacks against US cities hosting 2026 World Cup matches — the tournament that begins in two weeks and will be hosted by the United States, Mexico, and Canada. The threat appeared in the al-Naba propaganda publication, controlled by the terrorist group, and specifically mentions only American cities, according to Gazeta do Povo reporting. The publication describes the tournament as "a golden opportunity for the lone mujahid to revive and renew individual attacks, especially in the heart of America, which hosts games in eleven cities."

"O grupo terrorista Estado Islâmico, conhecido pela sigla ISIS, ameaçou a Copa do Mundo de 2026, que ocorrerá nos Estados Unidos, no México e no Canadá, em uma publicação semanal digital divulgada nesta quinta-feira (18/6)."

Gazeta do Povo

"O grupo terrorista citou cidades americanas que recebem jogos do torneio da Fifa e incentivou ataques de lobos solitários contra multidões."

DCM

"Esta temporada é uma oportunidade de ouro para o mujahidin solitário reviver e renovar ataques individuais, especialmente no coração da América, que sedia jogos em onze cidades"

The ISIS text called for "lone wolf" attacks — actions carried out by radicalized individuals without centralized coordination — and mentioned methods such as knives, vehicle ramming, and arson. The group also criticized the tournament in religious terms, stating that "sport does not justify wasting time and prayers spending hours in front of screens."

"O grupo terrorista citou cidades americanas que recebem jogos do torneio da Fifa e incentivou ataques de lobos solitários contra multidões. A publicação mencionou ações com faca, atropelamentos e incêndios, em uma tentativa de estimular ataques contra torcedores e áreas de concentração de público."

"O ISIS afirmou que o "esporte não justifica o desperdício de tempo e orações passando horas em frente à telas"."

The US hosts 78 of the 104 World Cup 2026 matches, while Canada and Mexico host 13 matches each. It is the largest edition in history, with 48 national teams — for the first time in the tournament.

"A Copa deste ano é sediada pelos EUA, México e o Canadá. A edição é considerada a maior da história, reunindo pela primeira vez 48 seleções de todo o mundo. Essa também é a edição com o maior número de partidas, 104. Os Estados Unidos recebem 78 jogos do torneio, enquanto Canadá e México sediam 13 partidas cada."

According to analysis by the Center for Strategic and International Studies (CSIS) published before the ISIS threat, the main terrorist risk for the 2026 World Cup comes from "domestic lone actors or small groups striking soft targets around the matches: fan zones, transit corridors, hotel and restaurant districts, and the queues outside stadium gates." The think tank notes that while jihadist threats from foreign groups are "degraded in recent years," several categories of foreign actors remain relevant: jihadist groups seeking attention and casualties, hostile states seeking disruption or retaliation, militants tied to overseas conflicts, and criminal organizations seeking leverage over their governments. ?

"The most likely danger to the 2026 World Cup comes from a domestic lone actor or small group striking soft targets around the matches: fan zones, transit corridors, hotel and restaurant districts, and the queues outside stadium gates."

Csis

"The international terrorist threat picture is diffuse. In 2026, no one foreign organization presents the kind of singular, overriding threat that al Qaeda did after 9/11 or the Islamic State, also known as ISIS, did at the height of its external operations in the 2010s. Although this is a welcome development, several categories of foreign actors remain who could see attacking the World Cup as useful for different reasons: (1) jihadist groups seeking attention and casualties, (2) hostile states seeking disruption or retaliation, (3) militants tied to overseas conflicts seeking to internationalize their grievances, and (4) criminal organizations, especially those in Mexico, seeking leverage over or revenge against their own governments."

The Islamic State lost territorial control in Iraq and Syria between 2017 and 2019, after an offensive by a US-led international coalition. The group once controlled approximately 100,000 km² of the two countries. Since then, it has concentrated part of its activities in Africa, particularly in the Sahel region. According to the Global Terrorism Index 2026, from the Institute for Economics and Peace, ISIS leads the list of the four deadliest terrorist groups in the world, responsible for 3,869 of the 5,582 deaths caused by terrorism in 2025.

"Entre 2017 e 2019, forças militares expulsaram o governo autodeclarado do ISIS dessas áreas. O grupo, que distorce valores do Islã para justificar violência, manteve células ativas mesmo após o recuo territorial no Oriente Médio."

DCM

"Com o enfraquecimento no Iraque e na Síria, o Estado Islâmico concentrou parte de suas atividades no continente africano, sobretudo na faixa conhecida como Sahel."

DCM

"Segundo o relatório Global Terrorism Index 2026, do Instituto para Economia e Paz, o Sahel concentrou mais da metade das 5.582 mortes causadas por terrorismo em 2025. O documento também aponta que o ISIS lidera a lista dos quatro grupos terroristas que mais matam no mundo, responsáveis por 3.869 dessas mortes."
