Top diplomats from the European Union's original six founding nations are meeting in Berlin for hastily arranged talks following Britain's stunning vote to leave the bloc.

German Foreign Minister Frank-Walter Steinmeier says it is critical to see the vote as a wakeup call. He was heading into meetings Saturday with his counterparts from France, Netherlands, Italy, Belgium and Luxembourg.

Steinmeier says EU politicians must listen "to the expectations of the European governments but also to the expectations of the people."

He cautioned against rash decisions, saying that "it's totally clear that in times like these one should neither be hysterical nor fall into paralysis."

Steinmeier's office says the meeting is one of many conversations now taking place, and shouldn't be seen as "an exclusive format."
