BANGKOK: Thailand is stepping up its flood response ahead of heavy rain forecast for Oct 4 to 5, with Prime Minister Anutin Charnvirakul ordering emergency assistance for vulnerable groups.

Anutin, who is also interior minister, said under the government's "leave no one behind" approach, authorities were ordered to ensure timely assistance for the elderly, bedridden patients, children and people with disabilities.

"Authorities should accelerate assistance to affected people nationwide and survey households that still lack essential supplies, particularly vulnerable groups," he said after a meeting of the National Disaster Prevention and Mitigation Command on Thursday.

He also ordered close coordination between provincial authorities and the military in carrying out flood-response operations, including evacuations and post-flood recovery efforts.
