A powerful explosion ripped through an industrial park in Argentina's Buenos Aires province on Saturday, igniting a massive fire.

More than 20 people were injured in the blaze, which also damaged several buildings. No one sustained life threatening injuries, local authorities said.

Dozens of fire crews were sent to control the blaze, which originated in Carlos Spegazzini, an industrial sector known for its petrochemical operations, some 50 kilometers (31 miles) south of the capital.
