(Reuters) - The United States is seeking “regime change” in Iran, President Hassan Rouhani said on Sunday, adding that the current U.S. administration is the most hostile that the Islamic Republic has faced in its four decades.

Tensions have increased between Iran and America after U.S. President Donald Trump withdrew from a multi-lateral agreement on Iran’s nuclear programme in May, saying it was flawed because it did not include curbs on Iran’s ballistic missiles programme or its support for proxies in Syria, Yemen, Lebanon and Iraq.
