International condemnations poured in after a terrorist attack during a military parade in southwestern Iran on Saturday killed 25 people and wounded more than 60 others.
United Nations Secretary-General Antonio Guterres offered condolences “to the families of the victims and to the Government and people of Iran.”
A statement issued Saturday by the UN said Guterres also "condemns the attack” in the city of Ahvaz and “wishes those injured a speedy recovery."
It was the deadliest terror attack to strike Iran in nearly a decade.
US officials reacted to the attack, saying that "the United States condemns all acts of terrorism and the loss of any innocent lives."
A US State Department spokeswoman also voiced support for "the Iranian people" following Saturday's bloodshed in the city of Ahvaz in Iran's oil-rich southwest.
Heather Nauert said: "We stand with the Iranian people against the scourge of … terrorism and express our sympathy to them at this terrible time."
French Foreign Ministry spokesperson Agnes van der in a statement issued late on Saturday offered condolences to the families of the victims as well as to the Iranian people.
"We are following closely developments in the site in connection with our embassy in Tehran," she added.
India Sunday denounced the Ahvaz violence. “India strongly condemns the dastardly terrorist attack in the city of Ahvaz, Iran,” the Ministry Of External Affairs said.
“We convey our heartfelt condolences to the Government of the Islamic Republic of Iran and families of the victims, and wish speedy recovery to those injured,” the ministry said in a statement.
Syria's Foreign Ministry in a statement Damascus condemns in the "strongest terms" the attack. The statement said those sponsoring "terrorism in the region won't be able to achieve their plots using these sordid crimes."
The attack was roundly condemned by other governments including Russia, the UK, Germany, Austria, Spain, Turkey, Qatar, Egypt, Kuwait, and Oman.
Amnesty International also condemned the armed attack. “Those responsible must be held accountable but in fair trials.”
Four terrorists attacked the parade commemorating the start of the 1980-1988 Iran-Iraq war in Ahvaz, capital of the border province of Khuzestan.
Officials said the gunmen were clad in Iranian military uniforms and had sprayed the crowd with gunfire using weapons they had stashed in a nearby park.
Iranian officials saw an Arab separatist group as the main suspect.
On June 7, 2017 in Tehran, 17 people were killed and dozens wounded in simultaneous attacks on Parliament and on the mausoleum of the founder of the Islamic Republic Ayatollah Rouhollah Khomeini – the first inside Iran claimed by the Daesh terror group.
