More than 100 dead, including bride and groom, in fire at Iraqi wedding hall

A bride and groom were killed along with more than 100 wedding guests as a fire ripped through a wedding hall in Hamdaniyah, in northern Iraq, on Tuesday, local officials said.

At least 150 others were injured when the wedding hall's ceiling caught fire and then collapsed, according to Hasan al-Allaq, the deputy governor of the Nineveh region.

Fireworks set off inside the wedding hall, where as many as 1,000 were celebrating, may have caused the fire, local reports said.

Fire investigators were working at the scene on Wednesday morning.

Iraq’s prime minister has called for three days of national mourning.
