A senior member of Iran's powerful Revolutionary Guard has been killed outside his home in Tehran by unidentified gunmen on a motorbike, state TV reports, giving only scant details about the attack.

The two assailants shot Colonel Hassan Sayad Khodayari five times in his car in the heart of the capital, state media said.

Reports identified Khodayari only as a "defender of the shrine," a reference to Iranians who fight against the Islamic State group in Syria and Iraq within the Guard's elite Quds force that oversees operations abroad.

There was no immediate claim of responsibility for the attack.

Security forces were pursuing the suspected assailants, state TV reported, without offering further details or giving a motive for the killing.
