The blaze broke out at the seven-story factory just outside Bangladesh's capital Dhaka late Saturday. More than 100 bodies had been found by Sunday morning.
The cause of the blaze was not immediately clear, and authorities have ordered an investigation.
Bangladesh has some 4,000 garment factories, many without proper safety measures. The country annually earns about $20 billion from exports of garment products, mainly to the United States and Europe.
