World leaders issue warning over broken Libya truce

World powers and regional actors overseeing Libya, meeting at the Munich Security Conference, have warned against the deteriorating situation in the North African country.

The German foreign minister, Heiko Maas, said those who break the UN arms embargo on Libya must be held accountable.

The UN deputy envoy to Libya, Stephanie Williams, said that last month's truce there had been violated more than 150 times already and that it was - as she put it - hanging by a thread.

Libya has been lawless since Col Muammar Gaddafi was toppled in 2011.
