BANGKOK – Thai Prime Minister Anutin Charnvirakul on Tuesday suspended the issuance of permits to buy ​firearms and said existing licenses would be ‌reviewed, days after a 14-year-old gunman killed nine people.

Anutin directed a deputy prime minister overseeing legal affairs to expedite ​a new gun control law, with stronger ​controls and significantly harsher penalties.

Police were ordered to stop renewing permits that enable people to ​buy firearms.

Registered firearms must be kept at home ​and cannot be carried in public, Anutin said, reiterating the current law.

For illegal firearms, studies are underway to enact legislation ​requiring their return to the state within ​a specified period, he said.
