REFILE-Death toll rises to 32 at petrochemical plant explosion
(Fixes typo par 3)
MEXICO CITY, April 24 (Reuters) - Four more people have been found dead after last week's explosion at a petrochemical plant in southeastern Mexico, raising the death toll to 32, state oil giant Pemex and Mexican plastic pipe maker Mexichem said in a joint statement on Sunday.
The vinyl petrochemical plant in the Gulf coast state of Veracruz is a joint venture between Pemex's petrochemical unit and majority owner Mexichem.
Pemex's CEO has said that last week's blast was caused by a leak but he did not know how the leak had happened exactly.
It was the latest in a series of fatal accidents at the company. (Reporting by Adriana Barrera and Luis Rojas; Writing by Joanna Zuckerman Bernstein; Editing by Michael Perry)
