"I think that truth and justice should prevail [in the case]. I hope that [Germany's] migration problems will not lead to an attempt to cover up what is really happening for some internal political reasons, that would be wrong," Lavrov said at a press conference dedicated to a review of the results of Russian diplomacy in 2015.
The Russian foreign minister also expressed hope that Germany would manage to cope with the migration influx without suffering "significant losses."
Europe is struggling to find a solution to a massive refugee crisis, with hundreds of thousands of refugees fleeing conflict-torn countries in the Middle East and North Africa. Germany received the most asylum applications in Europe last year.
