Pakistan's KSE-100 index (the benchmark of the Pakistan Stock Exchange) fell 1,742 points, or roughly 1%, on Monday, closing at 172,196 points as investors reacted to renewed uncertainty over the Middle East conflict. The decline was compounded by doubts over whether a second round of US-Iran talks, due to be held in Islamabad, will go ahead. The drop reverses part of last week's strong 4% weekly gain, and leaves the index some 15,000 points below its all-time high set in January.
