New British Foreign Secretary Boris Johnson, who recently likened the European Union to Adolf Hitler's vision for Europe, is in Brussels to meet with his new EU colleagues, and says he hopes to cooperate closely.

Johnson led a winning campaign to persuade voters to leave the European Union, but said Monday it "in no sense means we are leaving Europe."

Johnson says: "We are not going to be in any way abandoning our leading role in European cooperation and participation of all kinds."

He says the attack in Nice, France showed the need for European countries to coordinate their response to terrorism. Johnson said he would support an EU call for "restraint and moderation" in Turkey following the failed military putsch there.
