US Democratic presidential frontrunner Hillary Clinton has made an impassioned plea Saturday for global unity against radical Islam, a day after terror attacks killed at least 129 in Paris.

“We need to have a resolve that will bring the world together to root out the kind of radical jihadist ideology that motivates organisations like ISIS,” she said in opening remarks at a prime-time televised debate in Des Moines, Iowa.

The Islamic State group (ISIS or IS) claimed responsibility for the attacks Friday.
