April 13 (Reuters) - Wall Street's main indexes opened

lower on Monday after weekend talks between the U.S. and Iran

failed to deliver a deal to end the war, threatening a nascent

recovery in equities and risking a renewed bout of volatility.

The Dow Jones Industrial Average fell 198.4 points,

or 0.41%, at the open to 47,718.21. The S&P 500 fell 10.4

points, or 0.15%, to 6,806.47​, while the Nasdaq Composite

dropped 53.7 points, or 0.23%, to 22,849.23.
