Russian President Vladimir Putin said the terms of the ceasefire need to be worked out, including a mechanism to control possible breaches of the truce.
Kremlin spokesperson Dmitry Peskov said it’s important not to “get ahead” of the question of responding to the ceasefire, which was proposed by Washington.
The launch happened hours after South Korean and U.S. troops kicked off their large annual combined drills, which the North views as an invasion rehearsal.
