BANGKOK (AP) — Authorities say more than 90 people, including primary school students, have been sickened by a chemical leak from a Hong Kong ship in eastern Thailand.

Provincial disaster prevention chief Surinrat Suksap said Thursday that hazardous flammable liquids leaked out of containers on the ship that was anchored at a dock in Laem Chabang industrial seaport in Chonburi province.

She says villagers and students in nearby areas were exposed to the chemicals that spread inland.

Surinrat says the leak on the ship that was traveling from Jakarta, Indonesia, was sealed within a few hours. The chemicals are used for polymer manufacturing and in industrial production.

Laem Chabang is 116 kilometers (72 miles) southeast of Bangkok.
