Police in Bangladesh say at least seven people were killed and 25 others injured when a natural gas pipeline exploded in the southeastern city of chittagong on November 17.

The explosion reportedly occurred in a five-story building in chittagong. Police say the blast caused part of the wall of a nearby building to collapse. It was not immediately clear what caused the explosion.

Since the beginning of this year, there have been frequent accidents caused by gas explosions in Bangladesh. In October an old gas tank exploded in dhaka, the capital, killing at least seven people. In February, a gas explosion and fire in dhaka's old town killed 81 people.
