India's unemployment rate rose to 8.5 per cent in October - the highest since August 2016, and up from 7.2 per cent in September, according to data released by the Centre for Monitoring Indian Economy (CMIE) on Friday, reflecting the impact of a slowdown in the economy.

The country's infrastructure output fell 5.2 per cent in September from a year earlier, the worst performance in years, government data showed on Thursday.

The industrial output shrank at its fastest rate in more than six years in August.
