The Organisation of Islamic Cooperation (OIC) held an important summit in 2017 to discuss the issue of Jerusalem. This summit was called after the United States announced it would recognize Jerusalem as the capital of Israel.

Many Muslim countries gathered to talk about this decision and to find a common response. The meeting was very important for showing unity among Muslim nations.

This special summit was held in Istanbul, which is a major city in Turkey. Leaders from different Islamic countries attended the event there.
