July 6 (Reuters) - Hong Kong's benchmark index closed at a three-month low on Monday after the biggest one-day fall in three years, as investors worried that the Greek debt crisis could deepen.
The Hang Seng index fell 3.2 percent, its largest drop since May 16, 2012, to 25,236.28. The China Enterprises Index lost 3.0 percent to 12,231.43 points.
Hong Kong tracks global and regional markets, nearly all of which saw heavy selling after Greeks voted to reject conditions of a rescue package.
