So far this is the only Turkish paper reporting it:
Turkish President Abdullah Gul has accepted an invitation from his Armenian counterpart to watch the World Cup qualifier between the Turkish-Armenian national teams in Yerevan as the Turkish Foreign Ministry said the visit would contribute to renewed relations between the two countries, Vatan daily reported on Saturday.
Armenia however has not yet been informed of Gul’s decision, the report said, adding that the president is expected to make an official announcement next week.
Armenia President Serz Sargsyan invited Gul to watch the World Cup qualifying match between the two country's national teams on Sept. 6 to mark "a new symbolic start in the two countries' relations".
Gul had previously said that Sargsyan’s invitation is an example of contributions towards solving the problems that exist between the two countries and that an evaluation of the invitation was underway taking every possibility into account.
In a gesture of good faith, Armenia offered to lift all visa requirements and payments for Turkish citizens traveling to the capital Yerevan for the match, the report also said.
