US Secretary of State Marco Rubio said Tuesday Washington remained ready to mediate in the war between Russia and Ukraine.

Axar.az informs that Rubio’s offer came after Russia intensified strikes on Ukraine over the weekend, including firing its Oreshnik hypersonic missile and following a phone call with Russian Foreign Minister Sergei Lavrov.

"Every time you see these big strikes from one side or the other, it's a reminder of why this is a terrible war that's now gone on longer than the Second World War, and it needs to come to an end," Rubio told reporters during an official visit to India.

"The US stands ready and prepared to help do whatever we can to help facilitate the end of this war, and hopefully the opportunity will present itself at some point," he said.
