The White House says, the United States President Barack Obama will not attend Lech Kacyznski's state funeral today because of the travel chaos across Europe. Other figures unable to attend include the Britain's Prince of Wales, French President Nicolas Sarkozy and German Chancellor Angela Merkel. Most of Europe's major airports remain closed because of a volcanic ash cloud. Thousands of mourners in Warsaw were at an evening Mass for Mr Kacyznski who died with 95 others in an air crash. His coffin, with that of his wife, has been taken to the city's cathedral, where it will remain overnight before being flown on today to the historic city of Krakow for the state funeral. All airports in Poland remained closed yesterday, including Balice in Krakow where most of the dignitaries were to arrive today.<br/>
