The drone attack in Moscow did little damage to the city, but it brought the war in Ukraine to Russian land, leaving officials and civilians stunned.

The Russian president admitted that the mysterious attack showed that the capital's air defense umbrella needs "work."

The Russian leader is apparently avoiding trips out of the country because he “has no sense of security,” according to a new report.

Conspiracy theories abound as to who is behind the strikes, but the idea that all is going to plan is getting harder to sustain, says Russia researcher Jade McGlynn

While the Kremlin sought to play down the incident, some residents of the Russian capital told NBC News it had left them uneasy and concerned that more may be on the horizon.

An expert told Insider the strikes could be Ukraine's latest effort in their "thousand cuts" strategy of warfare to distract and alarm Russians.

At least eight drones were intercepted, the Kremlin said, but the foray raised questions about Russian air defenses.
