In separate statements, Abu Dhabi and Ankara strongly condemned the twin attacks, which killed 12 people and wounded 42 others.
On Wednesday morning, terrorists launched simultaneous attacks on Iran’s parliament building in downtown Tehran and on the mausoleum of Imam Khomeini, south of the city.
Four armed assailants, dressed as women, attacked the parliament building in the morning.
Equipped with AK-47 assault rifles, handguns and suicide vests, the gunmen killed security guards and ordinary people before holding people hostage in the upper floors of the building.
Security forces laid a siege to the parliament for several hours. Three of the gunmen were shot dead in an exchange of gunfire, while the other blew himself up.
The crisis came to an end at around 10:30 GMT.
The Daesh (ISIL) terrorist group has claimed responsibility for the attacks.
