US security agencies suspect Moscow behind drone incident at Leipzig airport

US security agencies reportedly believe Moscow was behind the explosive drone found at Leipzig/Halle airport near Ukrainian cargo planes, according to US media citing American officials. The Wall Street Journal reported the drone likely belonged to Russia's government, while CNN cited a US defense official saying it was from Russian intelligence. German authorities have been more cautious, calling it a "hybrid" attack by foreign powers. Russia denies involvement. Federal prosecutors are investigating attempted explosives and air-traffic interference. The drone was discovered Tuesday night near Ukrainian transport aircraft and brought down by an airport employee. Germany's federal prosecutor has taken over the case.
