Maritime & Ports Impact - yemen conflict

PVI agents report no change in the situation at Yemen's ports over the past seven days. Aden port remains closed and the Aden oil terminal is open. Balhaf, Malla and Ras Isa are closed while Hodeidah, Mokha and Saleef have remained operational. The situation surrounding Mukalla port remains unclear. Media reports indicate that the city is under the control of al-Qaeda in the Arabian Peninsula (AQAP) militants, however PVI's agents have reported that the port remains open. According to some local media reports vessels are en route to Mukalla port and unconfirmed press and social media reports indicate an oil tanker safely visited port in the past week.

Vessel Tracker information indicates that seven tankers are currently located in Yemen’s territorial waters, including three waiting to enter Aden, one waiting to enter Hodeidah and one waiting to enter Mokha. Coalition requirements that all vessels be searched and receive clearance prior to entering Yemeni ports have continued to cause delays, with the UN reporting on 27 April that an oil tanker had been waiting since 21 April to receive clearance to enter port. Prolonged delays, uncertain procedures and security concerns have seen many vessel operators withdraw from the country altogether.

Pro-Houthi forces reportedly gained control of an area west of Aden leading to the Bab el-Mandeb strait on 26 April. Further details about the development were not disclosed, though no disruption or threat to shipping traffic was reported as a result of the advance by pro-Houthi forces in the strategic area. Previous operations by Houthi rebels near the Bab el-Mandeb strait have prompted coalition air strikes and any activity by pro-Houthi forces in the area merits attention given the potential for shipping to be affected.

Iran's seizure of a Marshall Islands-flagged container vessel, the Maersk Tigris, on 28 April comes amid heightened tensions between Tehran and rival regional powers over the conflict in Yemen. Iranian vessels fired a shot across the bow of the vessel and forced it and the 24 crew members on board to Iran’s Bandar Abbas port. The vessel had reportedly been transiting the Strait of Hormuz, in position 27°02N – 056°16.27E, along an international shipping lane en route to Jebel Ali when the incident occurred. Officials in Tehran have said the seizure was a civil matter related to a complaint from an Iranian company but the situation nonetheless generated concern about freedom of movement in the region.


Intense fighting persisted across Aden during the reporting period with small arms fire and artillery attacks as well as air strikes reported across multiple areas of the city, including near the Aden port. There are reports that anti-Houthi forces have made notable gains in fighting over the last week and that Houthi rebels and allied military units have increasingly seen their supplies lines cut off. However there is no clear indication of a decisive change in the momentum of the conflict. Pro-Houthi forces have also begun enforcing an economic blockade in the northern areas of Aden they control.

Wider yemen Conflict

Saudi-led forces have continued intense air strikes against rival Houthi forces despite announcing on 21 April that military operations would be curtailed in favour of a greater focus on a political solution to the conflict. There has been no discernible progress toward ending the fighting and the humanitarian situation continues to worsen with Yemen’s exiled government declaring Aden, Taiz and Dalea to be disaster zones on 27 April. Reports that coalition forces had begun training and deploying anti-Houthi tribal forces in the Marib region is an indication of further escalation of the conflict against entrenched Houthi forces who have failed to be dislodged by weeks of air strikes.

On 25 April an affiliate of the Islamic State (IS) known as Wilyat Sana’a released a video officially announcing its presence in Yemen and declaring its intention to target Shi’a Houthi rebels. The message, which follows territorial gains by AQAP militants in the east and earlier claimed attacks by IS militants against Shi’a interests, is further indication of the extent to which the political upheaval in Yemen has enabled militant groups to expand their influence in the country. Saudi-led forces had said a key focus of the new phase of their military operation in Yemen would be counter-terrorism but to date no details about this mission have been disclosed. Continued advances by militants are likely to increase pressure on the coalition but it is unclear how they will respond as their focus remains primarily on reversing Houthi gains.
