Germany on Wednesday hailed a Russia-US deal to extend key nuclear pact New START, saying it offers "more security" for Europe. "At the beginning of a key year for disarmament and weapons control, the renewal is an important milestone," said Foreign Minister Heiko Maas in a statement. He added that action must be taken to "urgently reverse" decisions by Donald Trump to pull out of other treaties including the Open Skies Treaty and a centre-piece arms control agreement with Russia -- the Intermediate-Range Nuclear Forces (INF) treaty. hmn/dlc/bp
