The US military is preparing for a weeks-long operation against Iran. For this, President Donald Trump's order to attack is expected.

Axar.az reports that two unnamed US officials told Reuters.

According to the officials, this operation could turn into a more serious conflict between the countries.

The agency noted that the officials' statement shows the increased risks for the ongoing diplomatic process between the United States and Iran.

Officials say that this time the planning is more complex. One official said that during a sustained operation, the US military could strike not only the nuclear infrastructure, but also the Iranian government and security facilities.

Officials declined to provide specific information.
