BRUSSELS (AFP) - Armand Duplantis was kept waiting a long time in Brussels as he failed in another bid to better his own world record of 6.18 metres, but the Swede is confident he will add at least another centimetre to the mark.

As a slight chill settled in at the King Baudouin stadium on Friday (Sept 3), Duplantis was forced to don his tracksuit as technical officials struggled to raise the bar.
