GENEVA — U.S. and Ukrainian officials concluded talks in Geneva on Thursday to discuss advancing efforts to end Russia's four-year invasion of Ukraine, just as Moscow signalled it was in no hurry to sign a deal. An AFP reporter saw the U.S. delegation leaving Geneva's Hotel des Bergues, the venue of the talks, and the Swiss agency ATS-Keystone published a photo of the Ukrainian lead negotiator, Rustem Umerov, leaving the hotel. US leader Donald Trump is pushing for an end to Europe's deadliest conflict since World War II, but has so far failed to broker any deal between Moscow and Kyiv. Previous rounds of US-led negotiations between Russian and Ukrainian officials in Geneva and Abu Dhabi have failed to yield a compromise, including on the key sticking point of territory. Russia, which has signalled it will not budge on its demands for full control of Ukraine's eastern Donetsk region, said Thursday it was too early to forecast when a deal would take place.
