U.S. condemns attacks in Iran: State Dept.

The United States condemned a militant attack in the Iranian capital of Tehran on Wednesday, the State Department spokeswoman said in a statement.

"The United States condemns the terrorist attacks in Tehran today," said Heather Nauert, the State Department spokeswoman. 

"The depravity of terrorism has no place in a peaceful, civilized world."

Suicide bombers and gunmen attacked the Iranian parliament and the Mausoleum of Ayatollah Khomeini in Tehran on Wednesday, killing at least 12 people in a twin assault which Iran's Revolutionary Guards blamed on regional rival Saudi Arabia.
