India's benchmark index Sensex rose for a fifth session on Wednesday, tracking gains in other Asian equities as geopolitical tensions over North Korea's nuclear and missile programme receded.

Asian shares hit a 10-year peak with investors breathing a sigh of relief as North Korean fears eased slightly.

MSCI's broadest index of Asia-Pacific shares outside Japan was slightly lower, after earlier poking up to its highest level since October 2007.

On Tuesday, the S&P 500, Dow Jones industrials and Nasdaq Composite all marked record finishes.

The United Nations Security Council unanimously stepped up sanctions against North Korea on Monday over the country's sixth and most powerful nuclear test on Sept. 3, imposing a ban on the country's textile exports and capping imports of crude oil, Reuters reported.
