As France marks the 10th anniversary of the Bataclan massacres, another reminder has come of the permanence of the jihadist threat.

A former girlfriend of the only jihadist to survive the November 2015 attacks has been arrested on suspicion of plotting her own violent act.

The woman - a 27-year-old French convert to Islam named as Maëva B - began a letter-writing relationship with Salah Abdeslam, who is serving a life sentence following his conviction in 2022.

When prison guards discovered that Abdeslam had been using a USB key containing jihadist propaganda, they traced its origin to meetings with Maëva B.

Following her arrest, investigators found evidence on her computer indicating possible plans for a jihadist attack. This has reignited concerns about the ongoing threats in France, marking this anniversary with heightened vigilance.

On the evening of 13 November 2015, coordinated attacks left 130 people dead, including 90 at the Bataclan concert hall. The memories of that dark day continue to resonate deeply.

Experts stress that, while the Islamic State group's fortitude has waned, the risk remains, often rooted in home-grown initiatives that exploit social networks.

The current political climate in France adds to these dangers, provoking fears of increasing radicalization amid social unrest.

Today’s commemorations will take place throughout Paris, culminating at the Eiffel Tower, which will glow in the colors of the French flag as a symbol of resilience and remembrance.
