I sat in the Observers Seat behind the Captain on left side of the aircraft for taxi; T/O; and climb to cruise for this flight. All was normal for these phases. I was assigned to be Relief First Officer on the return flight. I spent most of this flight in rest. Again I occupied the Observers Seat for the descent; approach; and landing. I arrived in the cockpit approximately 15 minutes before the descent. All appeared to normal. During the Approach Briefing there was concern expressed to a couple of facts. One; Runway XX was in use due to the weather had changed and blowing sand was now happening reducing visibility; and Two; concern to stay out of [Foreign] Airspace 15 [nm] to the east. The current visibility was such to where the airport could be and was acquired visually. The blowing dust was not as bad as reported. I saw the airport at 7 DME from the end of the runway. As did the Pilot Monitoring; and the Pilot Observer in the center seat. All appeared to be normal until about a 3 mile final. I ask the Observer in the center seat; does it look like he (The Captain; Pilot Flying) is lined up with the Runway? No. We agreed. I immediately said 'Captain you need to turn right and line up with the runway.' To my dismay he said; 'I can't see the runway.' I immediately told the Pilot Monitoring take the airplane and turn right to the runway and land. 1.5 mile final. Both the other Observer and myself said loudly go-around. The Captain then corrected the airplane saying 'I have it; I have it; I have it' and successfully landed the airplane. Then taxied to the parking stand without further ado.
B767 Relief Pilot reported flying pilot set up for landing to incorrect runway.  The crew corrected the issue and landed uneventfully.
