Narrative:

We were cleared for the ILS runway X at ZZZ. Called the tower at the marker. We had a visual on the airport and the tower instructed us to change runway to runway Y. We joined final for runway Y and were on about 3 mi final when I saw an aircraft taxi into position. I asked the controller if that was an airplane on the runway. He said don't worry; the aircraft will be gone when you land. 10 seconds later we were instructed by the tower to go around. We went around; complied with altitude and headings once we had that from the tower. I declared minimum fuel. I thought about getting vectors back around in ZZZ1; but we were at the point I decided to divert to our alternate of ZZZ. Landed in ZZZ with 3100 pounds of fuel. Our planned reserve fuel was 3050 pounds.
