Defiant Donald Trump dominates US Republican TV debate

Donald Trump continued to dominate the Republican race for US president by causing further controversies in the first debate.

When the debate ended, commentators immediately praised the performances of Florida Senator Marco Rubio and Ohio Governor John Kasich.
