Iran’s military kicked off a ground forces drill on Tuesday along the coast of the Gulf of Oman.

Axar.az reports this was reported by state TV.

The latest in a series of snap exercises that the country is holding amid escalating tensions over its nuclear program and Washington’s pressure campaign against Tehran.

According to the report, commando units and airborne infantry were participating in the annual exercise, along with fighter jets, helicopters and military transport aircraft. Iran’s National Army chief Abdolrahim Mousavi was overseeing the drill.

Iran has recently stepped up military drills as part of an effort to pressure President-elect Joe Biden over the nuclear deal that President Donald Trump pulled out of. Biden has said the US could rejoin the multinational accord meant to contain Iran’s nuclear program.
