Tehran: The acting chief of Iran’s air force says his pilots will hold a military drill over the strategic Strait of Hormuz, the waterway for one-fifth of the world’s oil tanker traffic.

Gen Ali Reza Barkhor says the manoeuvres are part of annual exercises meant to show off Iran’s air defence capabilities and military readiness.

Barkhor told state TV on Thursday that the exercise will also extend into the Arabian Gulf waters. In past years, Iran had threatened to block the waterway in retaliation for international sanctions over its controversial nuclear programme, but Tehran no longer issues such warnings.

Barkhor says the two-day drill is to begin on Friday.

Iran’s air force has US and Russian-made fighter planes as well as their home-made replicas.
