Democratic congresswoman and "Squad" member Cori Bush has lost her primary race in Missouri, according to US media projections.

Wesley Bell, a St Louis prosecutor, will instead be the party's candidate in the state's first congressional district this November.

Ms Bush came to prominence as an organiser in the Black Lives Matter movement and, after taking office in 2021, as one of the "Squad" of Democratic members of the House known for supporting progressive causes.

She has been a vocal critic of Israel's war in Gaza, with pro-Israel groups spending more than $10m (£7.9m) on efforts to unseat her in the primary.

Projections from both the Associated Press news agency and NBC News suggest Mr Bell is on track to win the vote with 51% of ballots cast, compared to Ms Bush's 46%.

The district is a strongly Democratic area and Mr Bell will be expected to hold it at the coming election.

Almost all the money spent in campaigning against Ms Bush reportedly came from the American Israel Public Affairs Committee (Aipac). Aipac is a pro-Israel lobbying group and has vowed to spend over $100m to unseat progressive lawmakers who have spoken out against the war in Gaza, Politico reported.

It marks the second loss for the Squad - a group of nine progressive lawmakers in the US House of Representatives - in recent months.

In June, more than $15m was put into a successful bid to oust Jamaal Bowman, another critic of Israel, from his seat in New York. The figure was the most spent in any House primary in history. Mr Bowman was ousted just weeks after he was censured for pulling a fire alarm while the House was in session.
