Authorities have issued a second evacuation order in a week for residents of a city in the U.S. state of Texas after an explosion and fire at a petrochemical plant. Officials issued the order late on Wednesday in Port Neches after air monitors detected elevated levels of a cancer-causing petrochemical produced at the TPC Group facility that was struck by the blaze and blast. The fire at the 218-acre (88-hectare) plant, which was put out on Tuesday after burning for six days, had earlier prompted the evacuation of about 60,000 residents from several cities in southeast Texas.
