Will tension in the Gulf spiral out of control?

Iran seizes a UK oil tanker after Britain detained one of its ships.

When the UK seized an Iranian oil tanker two weeks ago, Tehran warned of retaliation.

It appears it's carried out that threat.

Iranian Revolutionary Guards detained a British vessel in the Strait of Hormuz on Friday.

Tehran said the Stena Impero was involved in an accident with an Iranian fishing boat.

A powerful council that works closely with Iran's Supreme Leader later said the seizure was a retaliatory act.

Britain's foreign secretary is worried Iran may be going down a dangerous path.

Can compromise be found before the situation spirals out of control?
