The relay was initially supposed to carry the torch around Islamabad, but the entire relay was cancelled due to security concerns regarding "militant threats or anti-China protests", and replaced by an indoors ceremony with the torch carried around the track of Jinnah Stadium. In fear of violent protests and bomb attacks, the torch relay in Pakistan took place in a stadium behind closed doors. Although the relay was behind closed doors, thousands of policemen and soldiers guarded the flame. As a consequence, no incidents arose.
