The vessel seized by Iran's Islamic Revolutionary Guard Corps had 23 seafarers onboard, of of Indian, Russian, Latvian and Filipino nationality.

In light of this incident, Mark Dickinson, Nautilus International General-Secretary, commented

We are shocked but not surprised by the developments in the Gulf ... We call on the UK government to urgently engage in diplomatic efforts for the release of the vessel and crew.

He continued that Nautilus has been raising its concerns along with the UK Chamber of Shipping repeatedly over recent weeks. The Secretary General added that their thoughts are with the seafarers and their families.

Furthermore, the ITF Seafarers’ Section chair David Heindel stated

The ITF is deeply concerned, the seizure of the Stena Impero marks a dramatic intensification in the turmoil in the region.

After seizing the vessel, the Islamic Revolutionary Guard Corps said that the Stena Impero was seized 'at the request of the Ports and Maritime Organization's office of Hormuzgan province for disregarding international maritime rules and regulations as it was passing through the Strait of Hormuz.'

Mr Heindel also called for the de-escalation of the increasing tensions in the area, and highlighted that all nations should support stability, ensure safe passage, and freedom of navigation in international waters throughout the Arabian Gulf, Strait of Hormuz, the Bab el-Mandeb Strait and the Gulf of Oman.

Mr Heindel concluded

Seafarers are concerned about the risk to their safety, it’s essential that the maritime industry and governments work collectively to guarantee safe passage and defuse conflict in such a vital region.
