Western security officials report that two incendiary devices, sent through DHL, were part of a covert Russian operation intended to ignite fires on cargo or passenger planes bound for the U.S. and Canada.

According to officials, the plot marks an escalation in Moscow's ongoing sabotage efforts targeting Western countries. The incendiary devices, designed to ignite mid-flight, were intercepted before they could reach their intended targets, preventing potential onboard fires.
