Tran Minh Khoi, first secretary in charge of consular affairs at the ministry, said after learning about the incident, the embassy reported it to the Vietnamese Ministry of Foreign Affairs and informed agencies concerned at home to verify the information about the 12 victims and their families.

The embassy also visited the seven Vietnamese crew members who got injured in the gas blast, he added.

For the five Vietnamese killed in the explosion, it has coordinated with the Jordan side to accelerate visa procedures for representatives of Vietnamese companies that sent the crew members to go to Jordan for post-death procedures.

According to Khoi, the seven are staying in a hotel after hospitalisation, and the embassy will continue its coordination with local agencies as well as its support to the companies in citizen protection.

The Jordan News Agency (Petra) cited Prime Minister Bishr Khasawneh as saying that the fact-finding team that was assigned to the investigation of the incident has been working "around the clock to achieve full results on the incident."

Khasaeneh extended condolences to the families of the Aqaba port victims and wished a speedy recovery for the injured.
