Wall St opens sharply lower on China woes

New York - US shares headed sharply lower for a third day in opening trade on Friday as China's economic troubles fueled another day of equity selloffs around the globe.

The selling pummeled shares across the board, with tech stocks hit hardest.

Ten minutes into trade, the Dow Jones Industrial Average was down 161.82 points at 16 828.87, reaching its lowest level in 10 months.

For the second day shares of aircraft maker Boeing, sensitive to the Chinese market, led falling shares on the blue-chip index with a 2.4% decline.

The broad-based S&P 500 dropped 0.89% to 2 017.58, while the tech-rich Nasdaq gave up 1.23% at 4 817.49.
