Leaders of the Gulf Cooperation Council (GCC) have rejected any fees on ships crossing the Strait of Hormuz, and called for a secure and free navigation in the waterway, the bloc's secretary-general said on Tuesday.

In a consultative meeting in the Saudi city of Jeddah, the Gulf leaders rejected Iran's closure of strait, describing the move as “illegal,” Jasem Mohamed Albudaiwi said.

The leaders also ordered swift steps for building a joint oil and gas pipeline, along with an early warning system to counter ballistic missiles, Albudaiwi added.

The Strait of Hormuz is one of the world’s most critical energy chokepoints, with roughly one-fifth of global oil supply passing through it daily prior to the start of the war between Iran, the US and Israel.

The waterway has faced disruptions since early March following the outbreak of the war. The conflict is currently on hold under a ceasefire, while diplomatic efforts are ongoing to reach a lasting agreement. (AA)
