Turkish President Recep Tayyip Erdogan says Turkey could take in leaders of Egypt's Muslim Brotherhood group who have been asked to leave Qatar.

The leaders had sought refuge in Qatar following the ouster of Egypt's Islamist President Mohammed Morsi and the crackdown on his supporters.

But their presence in Qatar had severely strained Doha's relations with Egypt as well as with Saudi Arabia and the United Arab Emirates, all of which view the more than 85-year-old Islamist movement as a threat.

Erdogan told reporters on his return from a visit to Qatar that Turkey would "review case by case" any request for refuge in Turkey.

Pro-government Star newspaper on Tuesday quoted Erdogan as saying: "If there is no hindrance, then things could be made easier for them."
