BRUSSELS, March 9 (Reuters) - The EU must be prepared to project its power more assertively as it can no longer rely on a "rules-based" system against threats and must determine if its institutions and systems help or hinder its credibility, European Commission President Ursula von der Leyen said on Monday.

SYDNEY, March 9 (Reuters) - Global players' union FIFPRO said on Monday there were serious concerns for the welfare of the Iranian women's soccer team, as they prepared to return home after being labelled "wartime traitors" for refusing to sing their national anthem before an Asian Cup match.
