For Muslims around the world, Eid al-Adha is a time of celebration, marked with visits from far-flung relatives, gift-giving and elaborate feasts.
But this year, the joyous occasion was marred with bomb blasts and deaths in violence-plagued Afghanistan and Iraq, and in civil war-wracked Syria.
In eastern Afghanistan, a bomb placed under a stage killed the governor of Logar province as he was delivering an Eid speech inside a mosque.
In addition to Gov. Mohammad Arsala Jamal, the blast killed 15 others, police said.
In Iraq, at least eight people were killed and 19 others wounded when a bomb exploded outside a mosque in central Kirkuk, Iraqi officials said.
The bomb went off as worshippers were leaving the mosque, police said.
And in Syria, where a bloody civil war continues to claim lives daily, three children were killed in an explosion that anti-government activists blamed on President Bashar al-Assad's regime.
