Ukraine may revise its ceasefire offer to Russia if the UN security council fails to pass a resolution urging a full and ⁠unconditional end to ⁠the ​hostilities, Kyiv’s envoy to the UN has warned. Ukraine had changed ​the dynamic in the war with recent strikes, said Andrii Melnyk, adding that some 40% of Russia’s oil refineries had been damaged.

Melnyk told a security council session that Ukraine stoody ready for direct negotiations with Russia but “our patience is not endless”. “If the security council would further choose a wait-and-see approach, I cannot exclude that Ukraine may recalibrate and modify its offer. Ceasefire along the de facto ‌front line is already a great compromise.”

The envoy’s statement reflects growing confidence that Ukraine’s war effort is on the front foot, with Russian cities starved of fuel supplies and a “middle strike” campaign seriously disrupting supply lines to Moscow’s occupying forces. The campaign’s success has prompted Russian-held Crimea to halt civilian gasoline sales, Pjotr Sauer writes. All summer camps in illegally annexed Crimea on Monday stopped accepting children and new bookings until 1 September for security reasons, said Sergei Aksyonov, the Russian-installed governor of the illegally occupied peninsula. Aviation authorities temporarily closed Moscow’s four airports on Monday as air defences battled a wave of Ukrainian drones.
