UN leader Ban Ki-moon said Tuesday he will press the foreign ministers of the United States, Russia, Britain, France and China to take joint action on the Syria crisis at a meeting next week.

He told a press conference the major powers had to take a "broader" look at the 30-month-old Syrian conflict and tackle the general surge in fighting and the mounting refugee and humanitarian strife.

The UN leader said he would meet with the foreign ministers of all five key nations in New York next week when world leaders gather for the UN General Assembly summit. UN officials said the meeting would be on September 25.

Ban is to meet separately with US Secretary of State John Kerry and Russian Foreign Minister Sergei Lavrov to discuss a possible peace conference to end what he called the "worst crisis we have experienced in many, many years."

The talks with Kerry and Lavrov are expected on September 28.
