State Department spokeswoman Heather Nauert says the US is sending thoughts and prayers to the Iranian people following attacks that struck Iran's parliament and the mausoleum of its modern founder.
Nauert says the US is expressing condolences to the victims and their families.
Nauert says that "the depravity of terrorism has no place in a peaceful, civilised world."
The US statement of solidarity with the attack's victims is notable because of the deep distrust between the US and Iran. The two countries don't maintain diplomatic relations and the Trump administration has emphasized the need to counter Iran's influence.
