Belgian federal police have detained four individuals, including one 18-year-old and three minors, on suspicions of plotting an Islamist terror attack on the Botanique concert hall in Brussels.

The apprehended suspects were reportedly exchanging messages that uncovered their attack plans, leading to charges of participating in the activities of a terrorist group.

This incident reflects Belgium's ongoing struggle with extremist activities, recalling the 2016 Islamic State-linked bombings at the Brussels airport and subway station.

In response to these arrests, the Botanique concert hall has reiterated its commitment to safety, confirming the implementation of advanced security protocols and continued cooperation with law enforcement.

Despite the recent security concerns, the Botanique venue remains operational, adhering strictly to safety standards, and has reinforced its security measures in the wake of past terror incidents.

The current national threat level in Belgium is maintained at 3, indicating a serious threat, though one level below the maximum threat level.
