BERLIN, Sept. 11 (Xinhua) -- Ukrainian Boxer Wladimir Klitschko defended his three heavyweight champion's belts against challenger Samuel Peter by technical knockout at the tenth round on Saturday night in Frankfurt.

Klitschko dominated the heavyweight world championship fight from start while the challenger tossed haymaker after haymaker into the air.

However, the match remained unspectacular and static due to the constant clinch by both sides.

Klitschko, 34, had no problems to finish the brawl at the tenth round with 1:22 minutes on the clock, defending his IBO ( International Boxing Organization), IBF (International Boxing Federation) and WBO (World Boxing Organization) champion's belts.

Peter, the 30-year-old challenger, was absolutely overwhelmed and had in no period the opportunity to threat Klitschko.

Klitschko defeated Peter the second time in his career to seal his 18th world championship fight.
