Cabo Delgado, Mozambique

What it is

Cabo Delgado is Mozambique's northernmost province, roughly 82,600 sq km of plateau, coastline, and ruby-bearing mountains bordering Tanzania. Since October 2017, an Islamist insurgency has gripped the province, carried out by Ansar al-Sunna Wa Jama'a (ASWJ), locally called al-Shabaab, with no connection to Somalia's group of the same name. The group pledged allegiance to Islamic State in 2018; IS formally designated it Islamic State Mozambique Province (ISM) in May 2022. The insurgency is rooted in colonial-era marginalisation, the Mozambican government's failure to channel gas and gemstone revenues into the local economy, and transnational jihadist networks that recruited across the Tanzania border from at least 2014.

History

ISM's first shots were fired in October 2017, when gunmen attacked three police stations in Mocímboa da Praia district. Attacks remained low-level through 2018 and 2019; IS claimed its first Mozambican operation in June 2019. The insurgency escalated sharply in 2020 as ISM seized territory, beheaded civilians, and burned villages across northern Cabo Delgado. The critical inflection came in March 2021, when ISM overran the town of Palma, killing at least a dozen civilians including foreign energy workers. TotalEnergies declared force majeure and suspended its US$20 billion Afungi LNG project. Rwanda deployed troops in July 2021; the SADC Mission in Mozambique (SAMIM) followed. The combined force gradually rolled back ISM's territorial gains through 2022 and 2023, but failed to eliminate the group. SAMIM largely withdrew in 2024; Rwanda's force of over 6,300 personnel remains the primary external counter-insurgency presence.

Current state

As of mid-2026, ISM has traded territorial ambition for sustained attrition. The group attacks Macomia town near-weekly, has detonated at least 45 recorded IEDs (ACLED data), and quadrupled kidnappings for ransom in 2025 compared with prior years, supplementing income from taxing artisanal mining sites. ACLED records 2,397 or more political violence events and 6,624 total fatalities in Cabo Delgado since October 2017, of which 2,768 were civilian. As of March 2026, roughly 474,000 people are displaced within Cabo Delgado, representing 72% of all internally displaced persons in Mozambique. OCHA put the 2026 humanitarian response funding requirement at US$348 million; 900,000 people were in IPC Phase 3 or above food insecurity between October 2025 and March 2026. TotalEnergies has not restarted Afungi, and any restart is now notional for the early 2030s. Rwanda's continued deployment is conditional on the European Union guaranteeing sustainable funding, a question unresolved as of mid-2026.

Relationships

Rwanda is the dominant external security partner, deploying over 6,300 troops and police, mostly Rwanda Defence Force. The arrangement is transactional: Rwanda gains geopolitical standing and economic contracts while Mozambique gains a capable partner its own armed forces (FADM) cannot replace alone. TotalEnergies holds the upstream operatorship of Rovuma LNG (Area 1) and has the largest commercial stake, with the Afungi project frozen since 2021. IS central provides media amplification and ideological branding for ISM; the degree of operational direction from IS headquarters remains contested among analysts. Artisanal miners, ruby traders, and informal border networks intersect with ISM's revenue base, making purely military solutions structurally incomplete. The June 2026 IED campaign against Rwandan patrols illustrates the insurgency's capacity to directly test the external-force model.

What to watch

Whether the EU and Rwanda reach a sustainable funding agreement, which determines whether the 6,300-strong deployment continues. TotalEnergies' stated security criteria for restarting Afungi, and any further force-majeure signals. ISM's kidnapping-for-ransom escalation, a potential indicator of declining IS central financing. Any move by the Mozambican government toward dialogue, a debate that gained traction in early 2026 among analysts and aid groups after eight years of inconclusive military response. ISM's mobility between Macomia, Muidumbe, and the southern mining belt as a leading indicator of territorial ambition versus attrition posture.
