All flights involving the Kuching-Pontianak and Pontianak-Kuching sector has been cancelled until further notice, said Kuching International Airport (KIA) general manager Mohd Nadzim Hashim.

"All flights to and from Pontianak has been cancelled until further notice. There are no passengers stranded from the sector here since early notice was given," he said.

He said four flights that were scheduled to depart and arrive here (KIA) were delayed due to the haze this morning since visibility was reduced to just 800m.

He said the delayed flights were Kuching-Kuala Lumpur, Kuching-Sibu, Kuala Lumpur-Kuching and Sibu-Kuching.

"The delay involved 333 passengers," he told Bernama when contacted.

Mohd Nadzim said flight MH2542 from Kuala Lumpur to Kuching with 65 passengers on board was diverted to Sibu, due to the worsening haze condition in Kuching.
