* Russia has no moral right to sit at the Group of 20 nations while it presses on with its invasion of Ukraine, Britain's foreign ministry said, hours after G20 host Indonesia said President Vladimir Putin would attend the group's November summit in Bali. * Putin warned his French counterpart, Emmanuel Macron, that shelling of the Russian-controlled Zaporizhzhia nuclear power plant in southern Ukraine, which he blamed on Kyiv, could result in a large-scale disaster. According to Macron's office, Putin agreed to an International Atomic Energy Agency mission to the plant.

* President Joe Biden's latest security assistance package for Ukraine includes surveillance drones and for the first time mine-resistant vehicles, a senior U.S. defence official said. ECONOMY

Russia remained China's top oil supplier for a third month. * S&P Global raised Ukraine's foreign currency credit ratings above "selective default", noting that Kyiv had completed a distressed debt restructuring.
