The Singapore government has decided to tighten maritime security by putting more barriers to prevent illegal entry.
"The government will also review maritime security in the coming months," Deputy Prime Minister and Minister for Home Affairs Teo Chee Hean said in parliament Tuesday.
The decision has been taken after three foreigners illegally entered Singapore through Raffles Marina in August, Strait Times reported.
An additional 80 km of land and sea-based barriers, such as fences, will be installed. That will result in 143 km of barriers around Singapore's 193 km coastline, said the deputy prime minister.
The additional barriers will help security agencies to focus their attention on areas and vessels that are more likely to pose a threat, said Teo.
