Two blasts have rocked Ukraine just hours after a car belonging to a pro-Russian rebel leader was blown up in a suspected ruse to give Vladimir Putin an excuse for war.
Defense ministers have held talks over fears that Russia could be seeking to send its troops into Ukraine. Moscow says it has withdrawn some forces and that it has no plan to launch an invasion.
Few world leaders know Vladimir Putin better than Finnish President Sauli Niinistö. In an interview, he tells DER SPIEGEL that the Russians are willing to pay a high price for things that are important to them.
Russia has positioned about 130,000 troops - equipped with everything from tanks and artillery to medical facilities and logistical support - close to Ukraine's border.
