Europe: Further rallies and security alerts related to Israel-Hamas conflict likely across the region through early December /update 9

Further protests denouncing the Israel-Hamas conflict are likely across Europe through early December. Many pro-Israel and pro-Palestinian demonstrations have taken place in multiple cities across the region, including London, Madrid, Rome, and Stockholm, since the start of the conflict Oct. 7. Many of these demonstrations continue to attract tens of thousands of participants. Security forces usually deploy enhanced measures to respond to protests; police have arrested demonstrators displaying public support for Hamas, and in response to clashes and vandalism. While authorities in some countries, including France, Germany, Hungary, Switzerland, and Austria, have banned some pro-Palestinian demonstrations, many have still occurred in these countries, particularly in France and Germany. Nonetheless, permitted demonstrations occur amid tight security and specific restrictions; multiple violators have been arrested.

Likely protest locations include public squares, city centers, government buildings, major transport hubs, mosques and Islamic cultural centers, Palestinian diplomatic offices, and Israeli embassies or consulates. Protesters in Denmark and the UK have targeted defense industry companies linked to Israel; further, similar events are likely. Since late October, multiple groups have organized sit-in protests inside major train stations with little to no warning, causing disruptions within the stations but avoiding delays to trains themselves. In Turkiye, protesters have organized demonstrations at franchise locations of prominent Western-owned fast food and cafe companies, prompting the US Embassy in Turkiye to issue a warning advising visitors to exercise caution at such locations. Protests have also occurred in Turkiye at US government and military facilities. Such events may spread to other countries. Incidents that cause significant loss of life in either the Gaza Strip or Israel will likely spark impromptu protests. Clashes between rival groups of demonstrators or between demonstrators and law enforcement officers are possible. Localized road travel delays are likely near any protests that materialize.

Additionally, increased security threats amid the ongoing conflict in the Middle East, as well as in the wake of terrorist attacks in France and Belgium, and incidents of targeted arson in multiple countries, will continue to prompt national governments to raise security alert levels. German authorities warn of increased risks of terrorist attacks in Germany as of late November. Authorities in Austria, France, and Portugal have raised their terrorism threat warning levels, while Spain has increased security. Sweden has called on its nationals outside the country to remain vigilant after two Swedes were killed in the Oct. 16 attack in Brussels, Belgium. Israel's National Security Council has called on Israeli citizens in Turkiye to leave the country as soon as possible following violent protests outside Israeli diplomatic offices in that country. Authorities in multiple countries, including Denmark, France, Germany, Norway, the UK, and Sweden, have increased security force deployments and patrols outside some synagogues and mosques, as well as Israeli, Palestinian, Jewish, and Islamic interests. Authorities in France, Germany, and the UK report significant increases in antisemitic and Islamophobe crimes, including verbal abuse and vandalism. The US Embassy in North Macedonia has warned of an increased risk of terrorist attacks due to heightened global tensions.

Increased security will likely be deployed in Christmas markets and public events through early December due to the recent increase in terror-related risks. On Nov. 29 German authorities arrested two people in relation to the Islamic State (IS) reportedly organizing terrorist attacks in North Rhine-Westphalia and Brandenburg.

Security levels will likely remain elevated across Europe until authorities determine that the threat has abated. Increased security is likely around sensitive sites and potential targets, including government offices, religious centers, and police headquarters. Security-related disruptions are possible for international arrivals at airports, maritime ports, and land border crossings. There has been an increase in security incidents across the region amid the Israel-Hamas conflict. Schools, government buildings, train stations, and airports in several countries have received multiple bomb threat warnings throughout November.

Responses to potential security incidents, including suspicious packages and bomb threats, will likely be enhanced throughout the region in the coming weeks as a precaution. Organized gatherings such as conferences, religious and public commemorations, and sporting and other cultural events may be disrupted by additional security procedures. Precautionary security force reactions, including evacuations and search operations, will likely prompt short notice and short-term business and public transport disruptions.
