ACLED’s Conflict Index ranks countries based on deadliness, danger to civilians, geographic diffusion, and the number of armed groups. In the latest Index, the top five countries – all classified as “extreme” - remained unchanged from 2024 despite significant changes in the structure and scale of those conflicts.
The Index ranks Palestine at the top of its list. Gaza saw a decrease in conflict-related deaths in 2025 following the agreement of a ceasefire between Israel and Hamas in October, but nearly all Palestinian civilians were directly exposed to violence.
Four years after the 2021 coup, Myanmar’s military junta escalated its air campaign against resistance groups (including by adopting drone technology) and made advances in Mandalay and Shan states. In Western Myanmar, the Arakan Army consolidated control over Rakhine state and continued confrontation with Rohingya armed groups along the Bangladesh border.
Over the review period, analysts recorded 7692 conflict-related deaths in Syria, with political violence mainly stemming from instability following the deposing of Bashar al-Assad. Druze and Alawite factions clashed with security forces from the new regime, and Israel increased air strikes in the southern region to deter activity from the occupied Golan Heights zone.
Following the arrest of drug lord Ismael Zambada in the US in 2024, tensions within Mexico’s dominant Sinaloa Cartel precipitated a series of deadly clashes between the Los Chapitos and El Mayo factions for control of the group. The past 12 months also saw an 11 per cent increase in fatalities arising from violent engagements between state forces and armed groups.
Throughout 2025, jihadist militant groups such as Jama’at Nusrat al Islam wal-Muslimin and the Islamic State Sahel Province escalated attacks across the Sahel, including the Sokoto and Kebbi regions of Nigeria. As part of a southward expansion campaign, foreign nationals were the target of abduction efforts by associated criminal networks.
