An explosion did little damage inside a men's room at Los Angeles International Airport on Sunday evening; the cause of the blast was determined to be a dry ice bomb.

The Los Angeles Times reports that the explosion, which was created by filling a bottle with dry ice, occurred at about 7 p.m. in a restroom at Terminal 2, which is home to several international and domestic airlines.



Officials said an airport employee heard an explosion in a men's room and went to investigate. He discovered a 20-ounce plastic bottle that had contained the dry ice. The blast did no damage, and no injuries were reported.

After the explosion Sunday, operations were suspended in the terminal, and flights were delayed until about 8:45 p.m. as the Los Angeles Police Department bomb squad responded. Police estimated about four flights were affected.

Last month, a former Transportation Security Administration worker was arrested after making threats against the agency and LAX terminals.
