Saudi Interior Ministry said on Thursday that it killed two Islamic State (IS) terrorists in a raid in Mecca.
Another two IS members were arrested in a separate raid in Jeddah, Xinhua cited a report by local TV Al Akhbar.
The Mecca raid took place after hours of police chase when the suspected terrorists took a shelter at a house usually rented by road travellers.
The ministry announced last week the foiling of a terror attack that targeted an area in Asir region in the southwest of Saudi Arabia, in which the police killed two suspected terrorists and confiscated two cars as one of them was planted with explosives.
Saudi Arabia has reported many deadly attacks orchestrated by the IS through its sleeping cells in the country.
