Ukraine and Russia: What you need to know right now

* The United States said it would impose new sanctions on Moscow for the referendums and the European Union's executive proposed more sanctions, but the bloc's 27 member countries will need to overcome their own differences to implement them. FIGHTING * Kremlin spokesman Dmitry Peskov said Russia would need to keep fighting until it had taken control of all of Donetsk.

Moscow was poised to annex a swath of Ukraine, releasing what it called vote tallies showing support in four partially occupied provinces to join Russia, after what Kyiv and the West denounced as illegal sham referendums held at gunpoint. REFERENDUM * On Moscow's Red Square, a tribune with giant video screens has been set up, with billboards proclaiming "Donetsk, Luhansk, Zaporizhzhia, Kherson - Russia!" * The head of the upper house of the Russian parliament said it could consider the incorporation of the four regions on Oct. 4, three days before Russian President Putin's 70th birthday.

* Residents who escaped to Ukrainian-held areas in recent days have told of people being forced to mark ballots in the street by roving officials at gunpoint. * The United States said it would impose new sanctions on Moscow for the referendums and the European Union's executive proposed more sanctions, but the bloc's 27 member countries will need to overcome their own differences to implement them.

FIGHTING * Kremlin spokesman Dmitry Peskov said Russia would need to keep fighting until it had taken control of all of Donetsk. Around 40% is still under Ukrainian control and the scene of some of the war's heaviest fighting.

* Ukraine's armed forces conducted strikes on Russian forces in four areas near the city of Kherson as part of their counter-offensive, while its aircraft hit six targets, said the Ukrainian Armed Forces southern command. * The United States is preparing a new $1.1 billion weapons package for Ukraine that will be announced soon, U.S. officials said.

GAS LEAK * Leaking gas bubbled up in the Baltic Sea for a third day after suspected explosions tore through undersea pipelines built by Russia and European partners. The Nord Stream 1 pipeline, once the main route for Russian gas to Germany, was already shut but cannot now be easily reopened.

* NATO and the European Union warned of the need to protect critical infrastructure from what they called "sabotage", though officials stopped short of assigning blame. (Compiled by Michael Perry)
