Mogadishu (Somalia Today) — Somalia has joined 15 international maritime treaties in the biggest legal overhaul of its waters since independence, raising questions over whether Mogadishu can now play a stronger role in policing one of the world’s most sensitive sea corridors.
The move comes as Western navies continue to track suspected arms shipments through the Gulf of Aden, the Arabian Sea and waters off the Horn of Africa, with Yemen’s Iran-backed Houthis a central focus of those efforts.
The federal government announced the accession on June 26 and later deposited the instruments at the International Maritime Organization in London.
Officials described the move as a sovereignty and commerce milestone for a country with the longest coastline on mainland Africa, but one that has struggled for decades to control its waters.
“Today is a great and historic day,” Ports and Marine Transport Minister Abdulkadir Mohamed Nur said after the London deposit.
He said the instruments would serve “diplomatic, commercial, defence” purposes and help protect Somalia’s sovereignty.
Legal gap
The package covers search and rescue, seafarer training, collision rules, maritime traffic, ship tonnage, safety at sea, oil pollution response and wreck removal.
But its most sensitive elements are the Convention for the Suppression of Unlawful Acts Against the Safety of Maritime Navigation (SUA) and its 2005 protocol.
The 2005 SUA protocol expands the convention from attacks on ships to the use of vessels for terrorism, weapons transport or proliferation.
It provides state parties with a common framework for criminalising offences, seeking extradition or prosecution, and cooperating on boarding requests when a flag state gives consent.
For Somalia, that matters because the legal weakness at sea has long matched the physical weakness on shore.
Its coast lies opposite Yemen and close to the Bab al-Mandeb, the narrow Red Sea entrance through which a major share of global trade normally passes.
The Houthis have used missiles, drones and explosive boats to pressure shipping since the Gaza war, saying they act in support of Palestinians.
In June, they again threatened Israeli-linked vessels in the Red Sea as regional tensions with Iran widened.
Iran route
Western navies and Yemeni forces have spent years intercepting dhows, fishing vessels and commercial cargo suspected of carrying Iranian weapons to the Houthis.
Tehran denies arming the group, but US and UN reporting has repeatedly pointed to Iranian-origin components in Houthi arsenals.
One of the most serious recent cases came in January 2024, when US forces boarded an unflagged dhow in international waters off Somalia.
Two US Navy SEALs drowned during the operation.
US investigators later said the vessel carried Iranian-made components for medium-range ballistic missiles and anti-ship cruise missiles.
Gen Michael Erik Kurilla, then head of US Central Command, said the seizure showed how Iran “actively sows instability throughout the region.”
A second January 2024 seizure by a US Coast Guard cutter in the Arabian Sea found more than 200 packages of missile parts, explosives, unmanned surface and underwater vehicle components, communications equipment and other military hardware bound for Houthi-controlled Yemen.
Those interdictions show why Somalia’s treaty move matters beyond Mogadishu.
Allied navies already patrol the Gulf of Aden and western Indian Ocean. Somalia’s accession now gives it a clearer legal partner when suspicious vessels move near Somali waters or rely on smuggling networks facing the Somali coast.
Smugglers adapt
Researchers and maritime security specialists say the route does not remain fixed.
When pressure rises on the direct Iran-Yemen corridor from Bandar Abbas to Houthi-held ports such as Saleef and Hodeidah, traffickers shift south, use mother ships off the Horn of Africa, or disguise cargo through commercial channels towards Djibouti before onward transfer.
Crew members from a seized vessel in 2025 described three routes, including a Somalia-linked corridor and commercial movement through Djibouti, according to maritime reporting.
The pattern matches a wider Gulf of Aden smuggling economy, where weapons, fuel, people and contraband often move through overlapping networks.
Security analysts have also warned that the Houthi pipeline not only supplies Yemen.
Some arms linked to Yemen-bound routes have surfaced in Somalia, where al-Shabaab, an al-Qaeda affiliate, taxes and exploits coastal and inland smuggling networks.
US intelligence and regional analysts have also reported discussions or cooperation between the Houthis and al-Shabaab, although evidence of direct large-scale transfers remains limited.
Hard part ahead
The treaty package does not automatically close the corridor.
Somalia still lacks a coast guard capable of controlling its 3,000 kilometres of coastline.
Federal authority remains uneven, regional administrations control key stretches of coast, and smugglers have long operated through clan, business and militant networks.
That is why the new legal architecture will depend on implementation.
Somalia must pass or update domestic laws, train prosecutors and maritime police, create reliable evidence chains and coordinate with foreign naval forces without fuelling accusations that it has outsourced sovereignty.
For Israel, the United States and Britain, the change still carries weight.
It moves Somalia from the edge of the maritime legal order into a framework allies can use to request cooperation, share intelligence and support interdictions.
For Mogadishu, the test is whether accession becomes enforcement.
Somalia has opened a legal door. It must now prove it can shut the weapons corridor that has used its coastline for too long.
