Criticism grows over violence at Donald Trump rallies

Presidential candidates for the 2016 race and other politicians are speaking out against Donald Trump after a string of violence at his rallies.

Mr Trump called off a rally on Friday night in Chicago after clashes between protesters and supporters.

The Republican who has won a string of primary contests has blamed the supporters of Democrat Bernie Sanders and denied responsibility for the violence. On Sunday, he said his campaign is "not provoking" and "wants peace".

A Quinnipiac University poll shows that Mr Trump is leading the way in Florida and tied with Ohio Governor John Kasich in Ohio ahead of crucial state primaries on Tuesday.
