An Iranian national suspected of working as a hitman for Ireland's notorious Kinahan criminal cartel has been shot dead in Dublin.

Hamid Sanambar, 41, was shot in the head and chest outside the home of his former driver, Sean Little, 22, on Tuesday, The Irish Sun reports.

Little was found dead from a gunshot wound on May 21.

It is believed Little's associates blamed Sanambar for both deaths and carried out the murder in retaliation.

Reports suggest that Sanambar, who worked as muscle for gangster “Mr Flashy," was attempting to clear his name in both of last week’s killings, by paying his respects at Little’s home, in Dublin city's Northside area.

Gardaí (Irish Police) say three masked men followed the hitman to the house and escaped in a 2004 Toyota Avensis which was later found burned out in a field.

Sanambar was an Iranian asylum seeker who had been living in Ireland for more than five years.

He had distinctive tattoos of a scorpion on his ear, as well as two teardrops under his eye.

Garda Detective Inspector Michael Mulligan said that investigators are considering if Sanambar and Little's murders are linked.

He said: "We're not giving any description of those involved at the moment for operational reasons.

"There were three persons who left the scene in the car after the shooting.

"This is a murder investigation that's being run here, we have adequate resources, national units are here with us as well.

"Naturally we're taking cognizance of the fact of where this murder happened."

"We're not connecting both at this time but it's something that we are considering.

Justice Minister Charlie Flanagan said it was unacceptable that there would be three murders in such a short space of time in Ireland.

He described the spate of chilling murders as a "matter of great concern."
