400 schools closed over pollution in Malaysia

Authorities have closed more than 400 schools in the Malaysian state of Johor after 75 students experienced breathing difficulties and vomiting.

Johor chief minister Dr Sahruddin Jamal said 75 students from 15 schools had complained of breathing difficulties and started vomiting.

The chief minister said they had all been taken to hospital.
