Tensions between Iran and the US have been simmering for most of the last century and they've taken centre stage today as the two face off in the World Cup. Most recently, Iran called for the USA to be kicked out of the contest after they shared an altered image of the Iranian flag as a show of support for women's rights in the Middle Eastern country.
Before that, the US imposed sanctions on Iran, asserting that Iran's morality police were responsible for the death of Mahsa Amini - who died after being arrested for wearing "unsuitable attire". This sparked protests, and at least a dozen people are believed to have been killed during the unrest.
But these are just the two most recent controversies in a long and troubled history that had its first major milestone in 1953, 69 years ago, when the US, alongside the United Kingdom, played a major part in the 1953 coup to ensure the rule of Mohammad Reza Pahlavi as Shah, which was met with resentment by many Iranian citizens.
