More than 400 schools in the Malaysian state of Johor have been closed after 75 students experienced breathing difficulties and vomiting.
Johor’s Chief Minister Dr Sahruddin Jamal says the exact cause of the ailments are not clear but it may be linked to a previous pollution case in March which left over 100 schools closed and thousands ill after inhaling toxic fumes from an illegal chemical waste river dump.
Malaysia’s Prime Minister Mahathir Mohamad says the latest incident should not have happened and vowed “stern action” will be taken against those responsible
