Exit polls in Ukraine suggest that the presidential election has been won by the pro-Moscow candidate Viktor Yanukovych. The unofficial polls indicate that Mr Yanukovych defeated his rival, the Prime Minister Yulia Tymoshenko, by three to six percentage points. Mrs Tymoshenko's campaign manager says the result is too early to call and has also alleged that extensive fraud has taken place. Richard Galpin reports from Kiev.
The results of the exit polls were released immediately after voting ended on Sunday night. Mr Yanukovych had been the front runner in the race all along. If his victory is confirmed by the Central Election Commission on Monday, it would be an extraordinary indictment of the failure of the leaders of the Orange Revolution to deliver on their promises over the past five years, which has left so many people here deeply disillusioned.

A huge search and rescue effort is underway at the Kleen Energy plant in Middletown, Connecticut. Emergency personnel are focusing mainly on one building which bore the brunt of the blast, which was reportedly caused by a gas pipeline explosion. The structure that suffered the most damage was apparently under construction, and there are concerns that there may be people buried under the steel and concrete. The massive explosion was felt nearly 50 kilometers away.
