"Loud sounds that Kerch residents heard an hour ago had nothing to do with the Crimean bridge. The attack threat alert has been sounded. After it is lifted, traffic will resume," Kryuchkov said on Telegram.
Kryuchkov added he could not confirm whether information on social media about explosions close to the bridge were true. The official recalled that an alert on the bridge sounds up to several times a day and asked residents not to escalate the situation as the information will be provided "immediately" in the event of emergencies.
The adviser further stated in a separate post on Telegram that "there was no direct attack on the Crimean bridge and no explosions in its vicinity."
He added that the bridge was closed for "the second or the third time today" due to a threat of an attack. The official reiterated that all services and ministries were in round-the-clock readiness in Crimea.
