"The investigators will be given access to data and information on military operations carried out on that day and on the scene of the incident, as well as in the surrounding area, which is at the disposal of the coalition," the communique read as quoted by the SPA news agency.
According to the UN estimates, the attack claimed over 140 lives and left more than 525 people wounded, while media reported on 213 deaths. The Saudi-led international coalition denied allegations of the Houthi rebels that it was involved in the incident.
Yemen has been engulfed in a military conflict between the government headed by Yemeni President Abd Rabbuh Mansur Hadi and Houthi rebels since 2014. The Houthis are backed by army units loyal to former Yemeni President Ali Abdullah Saleh.
Since March 2015, the Saudi-led coalition of mostly Persian Gulf countries has been carrying out airstrikes against the opposition Houthis at the request of Hadi.
