Spanish Prime Minister Pedro Sánchez on Wednesday joined a chorus of world leaders welcoming the announcement of a U.S.-Iran ceasefire but issued a thinly veiled swipe at the Trump administration for having initiated the hostilities.

“Ceasefires are always good news. Especially if they lead to a just and lasting peace. But this momentary relief cannot make us forget the chaos, the destruction, and the lives lost,” Sánchez said in a social media post, according to a translation.

“The Government of Spain will not applaud those who set the world on fire just because they show up with a bucket.”

Sánchez, who has emerged as one of the European Union’s leading critics of U.S. and Israeli strikes against Iran, called for “diplomacy, international law and PEACE” to prevail.

His comments come shortly after the U.S. president said he had agreed to suspend attacks on Iranian infrastructure for two weeks, sparking a broad-based relief rally across risk assets.
