Pop singer Whitney Houston has cancelled the Paris concert she was due to give Tuesday because of illness, the concert's organisers said. Houston was suffering from a respiratory infection and a new date would be announced later in the day, said the statement. The Paris concert, at the Paris-Bercy arena, was to have been the first date in a European tour. But the next concert in the tour, in Manchester, England on Thursday, was still set to go ahead, said organisers.
