Qassem Soleimani, one of the most celebrated military generals in Iran was killed in a U.S. drone strike at the airport in Baghdad
According to reports, the two countries are even ready to wage war against each other
Here's all you need to know about the events that have led to the current crisis
In fact, looking at the history of the two countries, most of it is filled with issues
In 1979, several Americans were taken hostage by the country. They were kept inside the US Embassy in the capital city of Tehran
There were hopes of a friendship between the two countries in 2015, when Iran reached an agreement with the US to reduce its nuclear capabilities
However, when Donald Trump got elected in 2016, the relationship went in a downward spiral
Trump has made it clear that he isn't in favor of the deal because he thinks it is the worst deal ever negotiated.
In 2018, Trump withdrew the United States from the Iran Nuclear Deal and reimposed sanctions on Iran
This was done to force the country's leaders to get aboard on a brand-new deal. But Iran rejected the offer, even though the economy was in terrible shape
In 2019, Trump decided to increase the pressure on Iran by applying sanctions on those countries that are doing business with Iran.
After this, about six oil tankers were destroyed in the Gulf of Oman. The US blamed Iran for the attacks.
In December 2019, an American contractor was killed in a rocket attack in northern Iraq. Washington said that an Iranian-funded military group was behind the attack
These constant bombings resulted in a backlash in Iraq. And as a result, the US Embassy in Baghdad was severely attacked by protestors.
Iranian officials said in a statement that it would take revenge for Soleimani's death
Two days later, the country eliminated all the limitations on its nuclear resources, particularly Uranium
Trump has said that if Iran retaliates, then the United States would respond in a 'disproportionate manner'
