Turkish President Recep Tayyip Erdogan has suggested that Turkey could take part in a future operation to liberate the Syrian city of Raqqa from Islamic State group militants.

Erdogan told journalists aboard a plane as he returned from a G-20 meeting that the issue was brought up by U.S. President Barack Obama during the meetings in China. His words were reported by Hurriyet and several other Turkish newspapers on Wednesday.

Erdogan says: "Obama wants to do some things jointly concerning Raqqa. We said this would not be a problem from our perspective."

The Turkish leader adds that he said Turkish and U.S. military officials could meet to discuss the issue.

Turkey's military entered Syria last month to back efforts by Syrian rebels to push IS from the border, and has also clashed with Syrian Kurdish troops.

The U.N. humanitarian aid agency says fighting in Syria's central Hama governorate has displaced some 100,000 people over eight days between late August and early September.

In a "flash update ," OCHA says figures from a camp coordination group show nearly half of the displaced arrived in the neighboring Idlib governorate. It says a shortage of shelter space means many displaced families are sleeping outdoors in parks.

The Tuesday update says the United Nations has sent an "inter-agency convoy with life-saving supplies to Hama" and was evaluating the humanitarian situation.

OCHA says a dozen schools in rural areas and four mosques in the city of Hama were converted into temporary shelters.

Insurgents led by an ultraconservative Islamic group last week advanced northward in Hama province, prompting fierce fighting with government forces.
