US Secretary of State Mike Pompeo on Monday denounced Iranian President Hassan Rouhani for his remarks calling Israel a “cancerous tumor”.

“Such statements inflame tensions in the region by seemingly calling for war. At an international conference on Islamic unity, Rouhani also encouraged Muslims worldwide to unite against the United States. This is a dangerous and irresponsible step that will further deepen Iran’s isolation,” said Pompeo in a statement.

“The Iranian regime is no friend of America or Israel when they repeatedly call for the death of millions, including Muslims. The Iranian people know better and do not agree with their government, which has badly represented them to the world for 39 years. The people have suffered under this tyranny for far too long,” he added.
