Iran's Revolutionary Guards said on Sunday that one of its officers, Colonel Sayad Khodai, was killed in a rare assassination in Tehran.
Khodai was "one of the defenders of the shrines", the semi-official Tasnim news agency reported, referring to military personnel or advisers who Iran says fight on its behalf to protect Shiite sites in Iraq or Syria against groups such as ISIS.
Two people on a motorcycle opened fire on Khodai, Tasnim reported, citing an informed source.
The Guards blamed Sunday’s killing on “anti-revolutionary” opponents of the government. The motorcycle attack was a reminder of killings of Iranian nuclear scientists which Iran has often blamed on Israel.
At least six Iranian scientists and academics have been killed or attacked since 2010, several of them by assailants riding motorcycles, in incidents believed to have targeted Iran’s disputed nuclear program, which the West says is aimed at producing a bomb.
