Tightly-controlled Singapore rolls out tough summit security

Concrete barricades will spring up at key sites and mechanical metal barriers that rise from the ground at the touch of a button are likely to appear on some roads.

Singapore’s reputation for rigid law and order was seen as a major factor for being chosen to host Tuesday’s US-North Korea summit - and the tiny city-state is determined not to disappoint.

Police, including elite units of Nepalese Gurkhas, will flood the streets and enforce a virtual lockdown of key sections of the city, blocking off roads to facilitate the historic face-to-face between President Donald Trump and North Korean leader Kim Jong Un.
