Police shot and wounded a woman in a Brussels suburb after she attempted to stab three people, according to local media reports.

The attack took place as passengers were disembarking a bus in the municipality of Uccle in the Belgian capital at around 5pm on Monday.

National broadcaster RTBF said that two of the victims have been taken to hospital with serious injuries, and one suffered a minor cut.

Police reportedly warned the attacker, who refused to comply, before shooting her in the arm.

Police sources have told RTBF that the woman was Asian and had a history of mental illness. Investigators do not currently believe that this was a terrorist incident.

The street has been sealed off, with multiple police patrols present at the scene. The bus route on which the attack took place has been suspended.

Belgium is on high alert following a string of terrorist attacks over the past year.

A man armed with a knife and shouting "Allahu Akbar!" launched himself at two policewomen on August 6 in the city of Charleroi. The perpetrator, who inflicted serious facial wounds upon one of his targets, was then fatally shot.

The deadliest attack happened in March, when five suicide bombers, who had pledged allegiance to Islamic State detonated nail bombs in Brussels Airport and a train station in the capital. Thirty-two victims were killed in the attacks.

The immigrant-populated Brussels district of Molenbeek has also been pinpointed as the heart of Europe's Islamist terrorist activity, after it was used as a recruiting center for IS jihadists, and the base from which last year's November attacks in Paris were plotted.
