BERLIN (Reuters) -A Ukrainian drone attack last weekend likely damaged around 10% of Russia's strategic bomber fleet and hit some of the aircraft as they were being prepared for strikes on Ukraine, a senior German military official said.

Many EU and Baltic countries fear a Russian attack. Germany says it is time to prepare shelters to protect the civilian population against attacks from Moscow

Germany has given Ukraine the green light to strike targets inside Russia using long-range weapons supplied by Berlin, in a decision that signals a notable hardening of Western resolve as the war grinds on.
