Turkey's foreign minister has shunned a security conference in Germany, citing the presence of an Israeli delegation.

Foreign Minister Mevlut Cavusoglu said Friday he decided not to attend the Munich Security Conference after organizers allegedly included an Israeli delegation to Middle East meeting at the last minute.

Relations between the two former allies have deteriorated over Israel's treatment of Palestinians and soured dramatically after Israeli commandos stormed a ship trying to breach a blockade of the Gaza Strip in May 2010, killing eight Turks and one Turkish-American.

Israel apologized to Turkey for the deaths under a U.S.-brokered agreement but reconciliation efforts have since failed.

In 2009, Turkish President Recep Tayyip Erdogan walked out of a World Economic Forum meeting in Davos, which was also attended by then-Israeli President Shimon Peres.
