Mumbai: The Bombay Stock Exchange benchmark Sensex fell by over 110 points in opening trade on Monday amid sustained selling pressure influenced by a weakening trend in the rest of Asia and worries over the euro zone debt crisis.

The 30-share Sensex, which has lost over 900 points in the past three sessions, fell by another 110.56 points, or 0.68 percent, to 16,051.50 in opening trade on Monday, with capital goods, metals, oil and gas and banking stocks leading the fall.

In a similar fashion, the wide-based National Stock Exchange Nifty index shed 35.60 points, or 0.65 percent, to 4,832.15.

Brokers said a weakening trend on other Asian bourses amid worries over the debt crisis in the euro zone mainly dampened the trading sentiment here, triggering selling by participants.

In the Asian region, Japan's Nikkei was down 1.65 percent in early trade on Monday. The Dow Jones Industrial Average in the US closed 0.35 percent higher on Friday.
