Muslims are celebrating one of the world's biggest religious festivals, Eid al-Adha, which marks the end of the hajj pilgrimage.
In Afghanistan, Muslims offered prayers in big mosques and visited relatives. Thousands of security forces have been deployed across the country to check subversive incidents.
Iraqis also commemorate the holiday amid tight security. It comes as the country's troops fight to retake territory held by Islamic State.
Celebrations were big in Indonesia, the world's largest Muslim-majority country. Aside from prayers, Muslims there slaughtered animals to be distributed to the poor -- an annual tradition in the Islamic world. The so-called Festival of Sacrifice will last until Sunday.
