Slovakia’s newly elected Prime Minister Robert Fico pledged on Thursday to stop delivering weapons to Ukraine, just one day after taking office.

The prime minister told lawmakers that Slovakia would “no longer supply weapons to Ukraine” and would only send humanitarian aid to Kyiv, according to French newswire AFP.

“I will support zero military aid to Ukraine … An immediate halt to military operations is the best solution we have for Ukraine,” said Fico, who has had a fractious relationship with Ukraine going back over a decade. “The EU should change from an arms supplier to a peacemaker,” he added.
