Germany believes there is a high probability that the Syrian military was involved in a recent deadly attack on a United Nations humanitarian aid convoy, German Vice Chancellor Sigmar Gabriel said Thursday in Moscow.
Gabriel urged Russian officials to conduct a thorough investigation of the incident, which killed at least 20 civilians near the war-torn Syrian city of Aleppo earlier this week.
Gabriel, speaking to reporters during a two-day visit to Moscow, condemned the attack as a "dramatic setback" for the peace process in Syria. "We are not able to resolve this conflict without Russia," Gabriel emphasized.
Gabriel met with Russian President Vladimir Putin the previous day for talks about the Syrian conflict, as well as ways to boost German-Russian economic ties.
Russia is a major ally of the Syrian government and, according to a recent pact with the United States, was supposed to ensure that Syrian warplanes would not fly over the area where the convoy was attacked.
Russia's Defence Ministry said Wednesday that it had evidence a US drone was flying over the area at the time of the attack. The US earlier claimed that Russia was responsible for the attack, even if it was committed by the Syrian military.
