Supporters and opponents of Republican presidential nominee Donald Trump clashed in the city of San Diego, California. Donald Trump was in the city ahead of California primary.
12 persons are arrested after the incident.
Trumpe has earlier pledged to build a border wall to keep out illegal immigrants from Mexico.
Trump backed out of an offer to debate with Democratic candidate Bernie Sanders.
"As much as I want to debate Bernie Sanders - and it would be an easy payday - I will wait to debate the first place finisher in the Democratic Party, probably Crooked Hillary Clinton, or whoever it may be," BBC reported quoting the Trump campaign team.
"Well Mr Trump, what are you afraid of?" Sanders reacted.
Trump has already got enough numbers to get the Republican nomination.
