On Monday, thousands of worshippers were seen at the Grand Mosque in Saudi Arabia's holy city of Mecca to perform the early morning special Eid prayers. Similar scenes were seen in and around mosques in other countries such as Egypt, Morocco and Jordan.
Eid al-Fitr is also usually marked with social gatherings, new clothes, and cookies filled with dates or nuts.
The holiday has brought joy, particularly to children, who receive candies and presents as part of the tradition.
