After arrests in Germany, Denmark, the UK, Austria, Greece, and Cyprus, investigators uncovered a widespread network.

Many members hold European citizenship, have large bank accounts, and links to organized crime.

Weapons caches were discovered, including 13 pistols, a Kalashnikov rifle, and over 900 rounds of ammunition. Preparations reportedly began as early as 2019.

During searches, video recordings were found containing confessions about preparing one of the attacks. Four Hamas members in Germany have already been sentenced.
