Ukraine has attacked a second Russian bridge in the Kursk region in a week as it continues its offensive across the border. Analysts say the incursion has put pressure on Russian forces across the frontline and forced Vladimir Putin to decide how to defend the border long-term.

The Ukrainian air force says it has attacked a second bridge in Russia’s Kursk region.

Footage posted on a commander’s Telegram channel shows an attack on a bridge in Zvannoe, Kursk over the Seym river.

This is the same river over which another bridge was destroyed earlier this week.

Ukraine’s destruction of infrastructure in the area is believed to be an attempt to hamper Russian supply lines or reinforcements.
