Iran’s Revolutionary Guards ratcheted up the tensions with Saudi Arabia as it accused its regional rival of involvement in Wednesday’s double terrorist attack in Tehran, which left at least 12 people dead and wounded more than 40.
Gunmen and suicide bombers launched simultaneous attacks on the parliament building in Tehran and the nearby shrine of Ayatollah Ruhollah Khomeini, the Islamic Republic’s founder.
The attacks were claimed by Isis, in what would be the jihadi group’s first significant strike in the Islamic Republic. However a statement from the Revolutionary Guards linked the “brutal attack” to Donald Trump’s visit last month to Riyadh, where the US president singled out Iran for fuelling “the fires of sectarian conflict and terror”.
