Following sanctions on Iran from USA and blaming it for 9/11 blast , pressured Iran to block the Harmuz oil route.  Around 97% of gulf oil passes through Harmuz and if that is blocked or threatened it will be treated as war ; said American officials.

American’s friends like Saudia, UAE  and OMAN are also worry if that block going to imposs by Iran.

Following days Iran has already started military drills in their own boundary but very close to international water. This was seen as an escalating step towards blockade.

Iran officials said that if West continously imposing sanctions , Iran will definately block this 97% oil route.

In the drill Iran uses its domestically built military weapon since it had sancations to buy military equipment from abroad.
