Warsaw - Numerous world leaders were forced to cancel plans to travel to Poland for the funeral of President Lech Kaczynski on Sunday, as volcanic ash from Iceland continued to ground flights to and from Europe. The White House said the United States would be represented at the funeral by Lee Feinstein, US ambassador to Poland. "I spoke with acting President (Bronislaw) Komorowski and told him that I regret that I will not be able to make it to Poland due to the volcanic ash that is disrupting air travel over Europe," Obama said in a statement. "Michelle and I continue to have the Polish people in our thoughts and prayers, and will support them in any way I can as they recover from this terrible tragedy," he added.
