Type 45 destroyer HMS Duncan arrives in Persian Gulf to escort UK tankers

A British warship dispatched to the Gulf to escort U.K.-flagged ships amid heightened tensions with Iran has arrived in the region, the defense ministry said.

HMS Duncan was sent to help accompany vessels through the Strait of Hormuz after Iran seized a British-flagged tanker there earlier this month, in what London called an act of "state piracy."

The destroyer joins Type 23 frigate HMS Montrose which is due to undergo maintenance in nearby Bahrain in late August. It will be replaced by another frigate, HMS Kent, later this year.

The United Kingdom has said it wants to establish a European-led maritime protection force in the Gulf to protect vulnerable shipping, while emphasizing it is not seeking a confrontation with Iran.

It has asked U.K.-flagged ships to give it notice when they plan to pass through the Strait of Hormuz, with HMS Montrose already having accompanied 35 merchant vessels during 20 separate transits, according to the Royal Navy.

"I'm pleased that HMS Duncan will continue HMS Montrose's fine work in helping to secure this essential route," Defence Secretary Ben Wallace said in a statement on Sunday, July 28.

"While we continue to push for a diplomatic resolution that will make this possible again without military accompaniment, the Royal Navy will continue to provide a safeguard for U.K. vessels until this is the reality."

Tensions have been escalating in the region for weeks, with U.S. President Donald Trump last month calling off at the last minute an airstrike on Iran over its downing of a U.S. spy drone.

Tehran has suggested the July 19 seizing of the tanker was in retaliation for U.K. Royal Marines helping Gibraltar authorities detain an Iranian tanker in the Mediterranean Sea two weeks earlier.

The U.K. said it had acted then because Iran was trying to deliver oil to Syria in violation of separate sets of European Union and U.S. sanctions.
