Mixed statements from Iran

TEHRAN: Iran's President Hassan Rouhani called for "regional and international cooperation and unity" after 12 people were killed Wednesday in twin attacks on Tehran claimed by the Islamic State group.
"Iran's message as always is that terrorism is a global problem, and unity to fight extremism, violence and terrorism with regional and international cooperation is the most important need of today's world," Rouhani said in a statement.
"Undoubtedly, today's terrorist incidents in Tehran will boost Islamic Iran's determination in the fight against regional terrorism, extremism and violence," he said.
Iran "will once again prove that it will break any plots and machinations by ill-wishers with more unity and integrity and its powerful security structure."
Twelve people were killed and more than 40 wounded in the attacks on Tehran's parliament complex and the shrine of revolutionary leader Ayatollah Ruhollah Khomeini.
Meanwhile, Supreme leader Ayatollah Ali Khamenei said the deadly attacks in Tehran claimed by the Islamic State group were mere "fire-crackers" that would have no effect on the Iranian people.
"The Iranian nation is moving forward and these fire-crackers that happened today will not have the slightest effect on the will of the people," Khamenei told students in the capital after the attacks that killed at least 12 people.
Earlier, Iran's elite Revolutionary Guards issued a statement vowing revenge for the twin attacks by the Islamic State group in Tehran, and said Washington and Riyadh were "involved".
"The Revolutionary Guards have always proven that they will never allow the blood of innocents to be spilt without revenge," they said.
"This terrorist action, coming one week after the meeting of the president of the United States with the leader of the one of the region's reactionary governments (Saudi Arabia) ... shows they are involved in this savage action."
Separately, the deputy chief of the Guards' Intelligence Service, Mohammad Hossein Nejat, told the Fars news agency that the men who attacked the parliament building in Tehran were aged between 20 and 25.
"(They) went to the parliament as visitors. The guards became suspicious of their bags and when they wanted to search them, shooting began and they killed the security guard," he said.
"The US and Saudi regime had ordered their stooges to do this."
He said the men spoke Arabic in the video released by IS from inside the building, but that their nationality was not yet known.
