The investigation was initiated in Spain, where police officers detected Spanish companies owned by Lebanese-born citizens trading in large quantities of parts and components for military drones able to carry explosives, the police said. Based on an analysis of documents detailing trades of the components within Europe, several hundred or even a thousand drones could have been assembled by Hezbollah using the parts, the Spanish police said in a statement. The light aircraft, which are hard to detect and stop, are loaded with explosives as heavy as several kilograms and sent into Israel, the police said. The remains of drones flown by Hezbollah and found in Israel match the type of components seized by the police in Spain and Germany, the statement said. Israel and Hezbollah have been exchanging fire since Hezbollah announced a “support front” with Palestinians shortly after its ally Hamas attacked southern Israeli border communities on Oct. 7, triggering Israel’s military offensive in Gaza. The fighting in Lebanon has killed more than 100 civilians and more than 300 Hezbollah fighters, according to a Reuters tally, and led to levels of destruction in Lebanese border towns and villages not seen since the 2006 Israel-Lebanon war.
