ISTANBUL - Turkish President Tayyip Erdogan said on Friday the Greek side was once again avoiding a solution to the Cyprus problem, warning that a solution without Turkey should not be expected. 'We have told Cyprus and Greece clearly that they should not expect a solution without Turkey as guarantor. We are going to be there forever,' Erdogan told reporters in Istanbul after Friday prayers. Speaking a day after U.N.-hosted talks broke up in Geneva, Erdogan said it was out of the question for Turkish troops to pull out of Cyprus unless both sides pulled out.
