Turkey has closed its airspace to Israeli military flights following a deadly raid on a Gaza-bound aid ship, the Turkish prime minister and officials said Monday.

Recep Tayyip Erdoðan told reporters in Toronto that Turkey imposed the ban after the May 31 raid on a Turkish ship that was part of a six-vessel international aid flotilla, according to Anatolia news agency. The prime minister, who is in Canada to attend a summit of the Group of 20 major industrial and developing nations, did not elaborate.

A Turkish government official said the ban was for Israeli military flights and that commercial flights were not affected. It was not a blanket ban and each flight request would be assessed case-by-case, the official added. The official spoke on condition of anonymity, in line with government rules that bar officials from speaking to journalists without prior authorization.

The Israeli prime minister's office had no comment on Erdogan's statements.
