Muslims around the world are celebrating Eid al-Adha, the feast of sacrifice, the second of two Islamic holidays celebrated worldwide marking the end of the annual pilgrimage or Hajj to the Saudi holy city of Mecca.

Across the world men, women and children prayed and sacrificed animals as part of the celebrations.

Eid al-Adha is the holiest of the two Muslims holidays celebrated each year. Photos from Pakistan show men in the street slaughtering goats, camels, cows and sheep as of the festivities.

As many as 10 million animals worth up to $3 billion are sacrificed during the festival, the Pakistan Tanners' Association says.
