Leaders are entering the final day of talks at the G20 meeting in Hamburg as officials try to bridge the gap with the US on issues such as trade and climate change.
German Chancellor Angela Merkel, who is hosting the summit in Hamburg, said the talks so far had been “very difficult”.
Negotiators worked through the night in an attempt to reach a compromise on the wording of the final summit statement.
It comes after a second night of violent protests on Hamburg’s streets.
The G20 (Group of Twenty) is a summit for 19 countries, both developed and developing, plus the EU.
