Ranked as one of the safest countries in the world, Singapore has been stepping up efforts to deter terrorism in recent years.
The proposals, which the city-state`s Straits Times newspaper said would apply to journalists and carry punishments such as fines or prison, were part of a Public Order and Safety (Special Powers) Bill 2018 introduced in parliament.
The measure would allow police to issue a "communications stop order", following approval from the home affairs minister, the Ministry of Home Affairs said in a statement.
That would "require all persons in the incident area to stop making or communicating films or pictures of the incident area, and stop communicating text or audio messages about the ongoing security operations in the incident area," it added.
The MHA said information leaks to terrorists could endanger the lives of security officers and people caught up in the attack.
As examples, it cited media coverage of a 2015 attack on a Jewish deli in Paris in which four hostages were killed and a 2008 attack in India`s financial capital of Mumbai in which 100 people were killed.
The terrorist threat facing Southeast Asia is growing as foreign fighters return to the region, regional defence ministers said this month in a joint statement, pledging to boost cooperation to tackle militancy.
