Three hundred schools in Kota Tinggi, Pontian and Pasir Gudang, which were ordered to close because of the haze problem on Friday, will reopen tomorrow following a drop in the Air Pollutants Index (API) readings for the three areas.

Johor education director Mohd Nor A Ghani said the district education offices and management of the schools concerned had been asked to inform parents or guardians on the development so that the 187,590 students affected could return to classes as normal.

However, he advised students with health problems like asthma to don face masks.

He added that activities outside the classroom, however, were still banned for now.

Meanwhile, the closure order on 117 schools in Kluang and 175 schools in Batu Pahat involving 134,872 students has not been withdrawn but has been extended to 171 primary and 40 secondary schools in Muar and Ledang following the haze emergency declaration for the two districts (Muar and Ledang) by Prime Minister Datuk Seri Najib Tun Razak today.

A total of 76,400 students and 6,846 teachers are affected by the emergency declaration.
