As the conflict in the Middle East enters its second month, all the major parties are doubling down on their positions, seemingly weighing the option of further escalation.

U.S. President Donald Trump threatened Monday to "completely obliterate" Iran's Kharg Island, a key oil hub, its power plants and oil wells if a peace deal with the United States is not "shortly" reached.

The US is reportedly weighing up an invasion or blockade on the Iranian island of Kharg, despite negotiations taking place between the countries.
