Niš

Nis is a city in Yugoslavia of Eastern Europe. The GDI forces have reported that Kane is inside the research lab in Nis and killing him with the destruction of the laboratory could eventually win the war and defeat the remaining Nod forces in the area.

First Tiberium War
The First Tiberium War's end soon became a reality. After the evacuation of Ignatio Mobius and his colleague from both Sofia and Shkoder, Delphi who was rescued from Nod forces in Corinth had sent intelligence files to Mark Jamison Sheppard and tasked James Solomon to destroy a research lab containing the staff of Kane's military inside the building. There were also surfaced reports that Kane is there on a visit to get more technologies acquired to defeat the GDI forces, but GDI under Solomon and Morelli officially attacked the Nod forces and the laboratory to rubble as the enemy retreated when their war was known to be lost out of hand. With the lab staff dead, Kane wasn't at the laboratory as said by Delphi but it soon became clear that Nod is retreating to Belgrade and the messiah is at a newly-built Temple of Nod at Sarajevo in Bosnia and Herzegovina.
