One Czech officially known to have died in Polish tragedy, two more feared dead

One Czech is officially known to have been among the 66 people who died when a hotel roof collapsed in the Polish city of Katowice on Saturday night. Meanwhile, a second Czech is believed to have been among the dead and yet another is unaccounted for.

The Czech president, Vaclav Klaus, sent his condolences to his Polish counterpart, Lech Kaczynski. Mr Kaczynski had been due to visit Prague on Monday but cancelled the trip after announcing a day of mourning in Poland.

A group of Czech rescue workers have been helping look through the rubble of Saturday's disaster in Katowice, which is near the Czech-Polish border.
