Europe has not witnessed a major coordinated terrorist attack so far this August, but that should not be confused with an absence of terrorist activity. Across the continent, security services have continued to investigate suspected plots, make arrests and track individuals believed to have links with jihadist organisations.
The picture emerging in August 2026 is of a threat that is fragmented, increasingly online and often detected before an attacker reaches the operational stage.
One of the more disturbing cases has emerged in France. French authorities are investigating a 28-year-old Afghan refugee living in Lourdes who is suspected of having travelled secretly to Afghanistan before returning to France.
The man, identified by French media as Awalkhan K., had received refugee status in France in 2023 after claiming that he was being persecuted by the Taliban. French investigators now suspect that he clandestinely returned to Afghanistan in late 2025 and may have received weapons or military training there.
The investigation reportedly began after jihadist material posted on TikTok was brought to the attention of the authorities. Investigators subsequently discovered photographs and videos allegedly showing him with Taliban fighters and weapons. He is also accused of publishing material praising the Haqqani network and Tehrik-e-Taliban Pakistan, or TTP.
He has been charged with offences including terrorist criminal conspiracy and advocating and financing terrorism. He denies the accusations against him and remains entitled to the presumption of innocence.
The French case is particularly important because it illustrates the increasingly complicated relationship between migration, foreign terrorist networks and online radicalisation. It also raises questions about individuals who have established themselves legally in Europe but retain or develop connections with militant networks abroad.
France had already faced another significant counter-terrorism case shortly before August. On July 25, authorities announced the detention of six people suspected of involvement in a possible attack against a synagogue in Sarcelles, north of Paris. The investigation followed the evacuation of around 300 people after a suspicious vehicle was discovered near the synagogue earlier in July. French prosecutors were examining the case as a suspected Islamist extremist plot.
Jewish institutions remain particularly sensitive targets.
In Britain, counter-terrorism police announced another development on August 20 in the investigation into the October 2025 terrorist attack against the Heaton Park Hebrew Congregation Synagogue in Manchester.
Hekmat Omar Ali Hakim, 49, was charged with failing to disclose information regarding terrorist activity. The original attack, carried out on Yom Kippur, involved Jihad Al Shamie driving towards the synagogue before attacking people with a knife while wearing what appeared to be an explosive belt. Two worshippers died and several others were seriously injured. Al Shamie was shot dead by police.
The new charge demonstrates how investigations into terrorist networks can continue long after an attacker himself has been killed. British counter-terrorism officers say the wider investigation remains active.
Germany presents a different but equally worrying security problem.
On August 5, German authorities began investigating an explosive-laden drone discovered near Ukrainian cargo aircraft at Leipzig/Halle Airport. The airport is one of Europe’s major freight hubs and has an important logistical role in supporting Ukraine.
German investigators specialising in extremism and terrorism became involved after explosives were reportedly discovered on the drone. The possibility of Russian involvement has been raised, although responsibility has not been established and Moscow has denied involvement in similar operations.
The distinction is important. Europe today faces not one terrorism problem but several overlapping forms of political violence: jihadist terrorism, violent far-right networks, attacks against Jewish targets, lone actors radicalised online and an expanding grey zone between terrorism, espionage and state-sponsored sabotage.
Germany has become particularly exposed to the jihadist dimension. In July, an Islamist attack connected to Berlin’s Pride celebrations killed one person and injured dozens. German Interior Minister Alexander Dobrindt described the incident as an Islamist terrorist attack.
The attack reinforced fears that the relative decline in jihadist violence after the destruction of the Islamic State’s territorial caliphate had created a misleading sense of security.
Europol’s latest terrorism assessment provides the broader context.
According to the European Union Terrorism Situation and Trend Report 2026, EU member states recorded 45 terrorist attacks during 2025 and arrested 486 suspects for terrorism-related offences. Of those arrests, 347 were associated with jihadist terrorism. Jihadists were also responsible for 24 of the 45 reported attacks.
The figures show that jihadism remains the largest terrorism-related arrest category in the European Union, even as European security agencies confront other forms of extremism.
Spain provides another indication of the scale of preventative operations. By early August, Spanish authorities said security forces had already conducted 43 counter-terrorism operations during 2026 resulting in 82 arrests for offences connected to jihadist terrorism.
This is the part of Europe’s terrorism problem that is often invisible.
A successful attack dominates television screens for days. An arrest in an apartment, the seizure of a telephone or the interception of communications between a teenager and an extremist recruiter rarely attracts comparable attention. Yet much of Europe’s counter-terrorism battle is now being fought precisely at this level.
The internet has also transformed the radicalisation process. Islamic State no longer requires control over Raqqa or Mosul to influence a young European thousands of kilometres away. Propaganda, encrypted communications, videos and social-media networks can provide ideological reinforcement without requiring membership of a conventional terrorist organisation.
This creates a difficult problem for intelligence agencies. A hierarchical terrorist cell can be infiltrated. A lone individual consuming extremist material online, moving between platforms and deciding independently to attack a synagogue, police officer, concert or public gathering can be considerably harder to identify.
Young people are increasingly part of this problem. In Britain, the Children’s Commissioner warned in August that referrals of children to the Prevent counter-radicalisation programme had risen sharply, from 2,918 in 2016-17 to 4,715 in 2024-25. Particularly worrying is the growing category of young people fascinated by extreme violence without necessarily subscribing to a coherent political or religious ideology.
Europe therefore faces a terrorist environment considerably different from that of the Islamic State’s peak a decade ago.
The threat has become dispersed rather than disappearing.
There are still individuals inspired by Islamic State and other jihadist organisations. There are networks connected to conflicts in Afghanistan, Pakistan and the Middle East. Jewish institutions remain under heightened protection. Far-right terrorism continues to concern European intelligence agencies. At the same time, Russia’s confrontation with Europe has introduced sabotage operations into a security environment already crowded with extremist threats.
The numbers underline why complacency would be dangerous. In 2025 alone, more than 70 per cent of terrorism-related arrests recorded by Europol were connected to jihadism.
Europe’s security services have prevented many potential attacks precisely because they have become better at identifying suspects before they strike. The absence of another Paris 2015 or Brussels 2016 should therefore not automatically be interpreted as evidence that the ideology which produced those attacks has disappeared.
August’s arrests and investigations suggest almost the opposite.
The terrorist threat confronting Europe has become quieter, more decentralised and more difficult for the public to see. But behind the relative calm of European streets, the counter-terrorism machinery remains very busy.
