Democratic presidential candidate Bernie Sanders reignited his race for the U.S elections with victories in the Idaho and Utah caucuses Wednesday, while his arch rival Hillary Clinton won the Arizona caucus. On the Republican side, controversial businessman Donald Trump kept his lead, winning in Arizona, while U.S. Senator Ted Cruz won the Republican caucuses in Utah.

Sanders took to Twitter to thank caucus voters in both states— "Thank you to all those who caucused tonight in Utah!...Thank you Idaho for our second big win of the night!"

However, the Vermont Senator's total of 930 delegates still fell considerably behind Clinton's 1,700 delegates.

Meanwhile, Trump defeated Republican competitors Cruz and Ohio Governor John Kasich in Arizona, inching closer to the magic number of 1,237 delegates. U.S. Senator Marco Rubio had dropped out of the presidential race last week.

U.S presidential candidates on Brussels attacks -

The Brussels terror attacks figured significantly in statements by Republican candidates, with Cruz calling for police to "patrol and secure Muslim neighborhoods" in the country, according to NBC News.

Trump pushed his demands on tougher torture in jails in the context of the Belgium attacks, claiming the blasts could have been prevented if Paris attack suspect Salah Abdeslam, who was arrested in Brussels last week, had been tortured for information, according to CNN

While addressing her supporters in Seattle after the Arizona victory, Clinton hit out at Trump's politics, especially in the light of the Brussels attacks Tuesday.

"We live in a complex and dangerous world. And we need a commander-in-chief that can provide leadership that is strong, smart and above all steady in taking on these threats. The last thing we need are leaders who incite more fear," she said, according to BBC
