BERLIN, Nov 15 (Reuters) - German Chancellor Angela Merkel and Belarus" leader Alexander Lukashenko held a phone call on Monday to discuss humanitarian aid for refugees and migrants stranded at the EU-Belarus border, a German government spokesperson said. The rare phone followed a decision by the European Union to step up sanctions against Belarus, which denounced as "absurd" Western accusations that it was driving a migrant crisis that has left thousands of people stranded in freezing forests on its borders with the EU. read more "The Chancellor and Mr. Lukashenko spoke about the difficult situation on the border between Belarus and the European Union - especially about the need for humanitarian aid for the refugees and migrants there," German government spokesperson Steffen Seibert said in a statement. Merkel and Lukashenko agreed to continue their exchange on these issues, Seibert added. The talks are the first contact between the Belarusian president and a western leader after presidential elections in Belarus in August 2020 at which Lukashenko claimed victory, igniting the biggest street protests in the country"s history.
