Mumbai, May 10 (IANS): The key Indian equity indices traded on a flat-to-negative note on Thursday afternoon due to weak global cues including high crude oil prices and geopolitical tensions after the US backed out of the 2015 Iran nuclear deal.

According to market analysts, heavy selling pressure was witnessed in metal, healthcare and consumer durable stocks.

However, gains in the major Asian equity markets somewhat supported the Indian indices.
