Diaplous Group has issued an alert regarding possible armed boarding and elevated piracy concern off Somalia.

According to the alert issued on 21 April, a possible armed boarding of an oil products tanker was reported about 24.0 nm southeast of Xaafuun (Hafun), Somalia, at around 12:00 UTC on 21 April 2026.
In the same wider area, a separate boarding of a Somali-flagged fishing vessel by eleven armed individuals was also reported yesterday, reinforcing concern that the incident fits an active piracy-related threat pattern.
To remind, according to the ICC International Maritime Bureau (IMB) piracy report for the first quarter of 2026, Somali maritime piracy activity continues, with two incidents reported off Somalia in Q1 2026 – one attempted attack and one successful hijacking.
Recommendations:
Primary shipboard safety measures
Vessels operating in the wider Xaafuun (Hafun), Somalia area should maintain heightened watchkeeping, restrict external access, rig physical barriers where practicable, and ensure citadel readiness in line with BMP MS 2025.
Reporting requirements and channels
Report immediately any suspicious craft, boarding indicators, or abnormal close approaches to UKMTO and MSCIO on VHF and through established reporting channels, preserving CCTV, log entries, and radar or AIS records.
Additional security measures and drills
Conduct security musters, verify emergency communications, brief crew on small-craft encounter actions, and prepare defensive measures and maneuvering responses appropriate to the threat environment under BMP MS 2025.
Communications and coordination guidance
Maintain continuous monitoring on distress and safety channels and VHF, coordinate closely with company operations and any naval reporting framework in the area, and avoid unnecessary close passing with unidentified small craft.
Any further general guidance
Pending authoritative clarification, masters should treat the wider Xaafuun sector as subject to elevated piracy-related uncertainty and consider tactical routing, daylight exposure reduction, and avoidance of unnecessary loitering near the reported position.
