In Asian markets, South Korea's Kospi, Japan's Nikkei 225 and Shanghai's SSE Composite index quoted lower, while Hong Kong's Hang Seng index traded in positive territory.

The US market ended mostly lower on Thursday.

"The recent US-Iran negotiations over Iran's nuclear programme concluded without a breakthrough, heightening concerns over the possibility of a US strike and the risk of a broader Middle East conflict.

"Amid rising uncertainty over the next US course of action regarding Iran, and in the absence of fresh domestic catalysts, investor participation is likely to remain cautious and selective," Ponmudi R, CEO of Enrich Money, an online trading and wealth tech firm, said.
