Gunmen killed at least 25 people and wounded 60 in an attack on a military parade in a restive Iranian province that is home to most of the country’s Arab minority, state media said.
The Islamic Republic News Agency reported the casualty figures at the parade in Ahvaz in southwestern Iran, and added that, with many of the wounded in critical condition, the death toll was expected to rise.
The dead and injured were a mix of members of the powerful Islamic Revolutionary Guards Corps and civilian onlookers, semiofficial news agencies reported. They included families that had gathered to watch the annual military parade.
The reports said that there were four gunmen wearing military uniforms and that security forces had killed two and captured the other two.
Some officials blamed Arab separatists for the assault, according to the news reports. State television described the attackers as “takfiri,” a term often used to describe Islamic State fighters. Both the Islamic State and a separatist group, Al Ahwaz, claimed responsibility.
The Iranian foreign minister, Mohammad Javad Zarif, wrote on Twitter that “terrorists recruited, trained, armed & paid by a foreign regime” were responsible. “Iran holds regional terror sponsors and their US masters accountable,” he said.
