"We have blocked Facebook temporarily and tomorrow we will call a meeting with other social media, like Twitter and Instagram, to ask for cooperation from them," Surachai Srisaracam, permanent secretary of the Information and Communications Technology Ministry, told Reuters.

"Right now there's a campaign to ask for people to stage protests against the army so we need to ask for cooperation from social media to help us stop the spread of critical messages about the coup," he said.

Print and broadcast media have already been instructed to refrain from critical reporting of the military's May 22 takeover.
