Putin vows to "intensify" strikes on Ukraine after Russian city shelled

Driving the news: Putin said during a New Year's Day visit to a Moscow military hospital that Ukraine should expect more strikes after the Saturday shelling of the Russian border city of Belgorod that killed 20 people and wounded more than 100 others — which he denounced as a "terrorist act" that he blamed on Kyiv.

• "They want to intimidate us and create uncertainty within our country. We will intensify strikes," Putin said. "Not a single crime against our civilian population will go unpunished."

Meanwhile, the Russian-installed official in the occupied Ukrainian city of Donetsk blamed Ukraine's forces for "heavy shelling" that killed at least four people on Monday.

Of note: Ukrainian President Volodymyr Zelensky in his New Year's Eve address promised Russian forces "will feel the wrath" of Kyiv's domestic weapons production.

• "Our weapons, our equipment, artillery, our shells, our drones, our naval 'greetings' to the enemy and at least a million Ukrainian FPV drones," Zelensky said, per a transcript.
• Kyiv typically doesn't comment on strikes on Russian soil.
