US President Joe Biden is projected to win Michigan's Democratic presidential primary comfortably, despite a significant protest vote over his stance towards the war in Gaza.

Activists have spent recent weeks urging Democrats to vote "uncommitted", and tens of thousands chose to do so, reports BBC.

He thanked "every Michigander who made their voice heard today".

The US is an ally of Israel, providing it with billions of dollars in military aid. Earlier this month the US vetoed a UN resolution calling for an immediate ceasefire in Gaza, while proposing a draft of its own, urging a temporary ceasefire.

The US position has angered many, including in Biden's own party, who want the president to take a stronger stance against Israel's military campaign.

In a statement that did not reference the protest vote against him, he hailed the achievements of his administration in the state and launched an attack against his rival Donald Trump.

Donald Trump is also projected to easily win Tuesday's Republican primary in the state, after what he called a "great day". "We're going to win big," he told a campaign celebration event.
