Indian shares fell for a third session on Wednesday, in line with the fall in Asian shares, on increasing tensions between the U.S. and North Korea after the two countries exchanged threats.
Global risk appetite faltered resulting in investors piling onto havens such as U.S. Treasuries, gold and the yen after Pyongyang saying it is considering plans to attack U.S. island territory Guam.
The threat from the Korean peninsula came just hours after U.S. President Donald Trump said in response to a Washington Post report on North Korea's nuclear capabilities that further threats from the country would be met with "fire and fury."
