Fires broke out at two factories in Pakistan Tuesday, killing at least 125 people.

More than 100 people were killed in the southern port city of Karachi when a blaze ripped through a garment factory.

The death toll rose early Wednesday after authorities pulled more bodies from the building. Many of the dead were found in the factory's basement.

Injured workers said they were unable to find a way out and jumped out of windows to escape, suffering broken bones. Parts of the building were still smoldering hours after the fire.

A cause of the blaze is not immediately known.

Karachi is Pakistan's most populous city and its commercial hub.

In the eastern city of Lahore, at least 25 people died Tuesday after being trapped inside a shoe factory. Local officials say the blaze was caused by a faulty generator.

It took fire crews several hours to bring the fire under control and rescue workers trapped inside the burning building.
