Germany's Economy Minister Robert Habeck on Sunday called for the strengthening of economic sanctions against Russia, following a "terrible war crime" that took place in Boutcha, Ukraine.

On Saturday, several corpses were discovered in Boutcha, a town northwest of Kiev, which was recently recovered from the Russians.

"This terrible war crime cannot go unanswered," argued Robert Habeck, in statements to the German newspaper Bild, also cited by the portal Eco Online. Given this, the Minister of Economy called for the "strengthening" of economic sanctions of the European Union against Russia.

Russia launched a military offensive in Ukraine on February 24 that killed at least 1,325 civilians, including 120 children, and wounded 2,017, including 168 minors, according to the latest figures from the UN, which warns that the actual number of civilian casualties is likely to be much higher.

The war has caused more than 10 million people to flee, including more than 4.1 million refugees in neighboring countries and about 6.5 million internally displaced persons.

The UN estimates that some 13 million people are in need of humanitarian assistance in Ukraine.

The Russian invasion was condemned by the international community at large, which responded by sending arms to Ukraine and strengthening economic and political sanctions on Moscow.
