Qatar is cautiously following recent developments in the Strait of Hormuz and previous events affecting regional and international shipping lines, the foreign ministry said.

The ministry stressed the need to contain these events urgently, expressing concern. The State of Qatar called upon all parties to exercise restraint and to work for a peaceful solution to these events.

The Qatari Foreign Ministry statement comes as tension in the region intensifies between Iran and the United States and Western powers, while the real importance of the Strait of Hormuz, the strategic waterway that accounts for about a fifth of the world's oil consumed, is emerging.

The wave of escalation, with the Iranian Revolutionary Guards holding a British oil tanker in the strait, said it had violated traffic regulations.

The latest developments in the context of Iranian threats and the ongoing closure of "Hormuz" began last round last year by the Iranian President Hassan Rowhani, who threatened to tighten control of the strait and prevent the export of Gulf oil to the world, followed by statements similar to a number of military leaders.
