Suspected Israeli warplanes bombed Iran’s embassy in Syria on Monday, a marked escalation in a war pitting Israel against its regional adversaries, and Tehran said the strike killed seven military advisers including three senior commanders.
Reuters reporters at the site in the Mezzeh district of Damascus saw emergency workers clambering atop rubble of a destroyed building inside the diplomatic compound, adjacent to the main embassy building. Emergency vehicles were parked outside. An Iranian flag hung from a pole by the debris.
Or anyone else everyone is basically already at war with. E.g. if Ukraine were to destroy the Russian embassy in North Korea, nothing would escalate past where it already is.
