"Naval forces from Jordan, Egypt, Sudan, Djibouti, Yemen, Somalia and Saudi Arabia as well as Royal Saudi Air Force planes are involved in the drills", Saqr Harbi told Asharq al-Awsat.
The exercise will wrap up on 26 September. Its goal is to bolster maritime security of the Red Sea nations, strengthen their cooperation and protect regional waters, he added.
The military exercises are held amid a row between Saudi Arabia and Iran that escalated tensions in the region. It started after attacks on Saudi Aramco oil compounds, which Riyadh blamed on Tehran.
The Islamic Republic denied the allegations, stressing that Houthi movement, which fights against the coalition led by the kingdom in neighbouring Yemen claimed responsibility for the incident.
The Red Sea countries formed an alliance in late 2018, with its first war games — the Red Waves 1 — held in December.
