Brazil's Lula calls on permanent members of UN Security Council to change behaviour

BARCELONA, April 18 (Reuters) - The five permanent members of the United Nations' Security Council should agree to change their behaviour after failing to stop the war in Iran, Brazilian President Luiz Inacio Lula da Silva told a progressive leaders' summit in Barcelona on Saturday.

"We cannot wake up every morning and go to bed every night with a tweet from a president threatening the world and declaring wars," Lula added in apparent reference to U.S. President Donald Trump without explicitly naming him.
