Deputy Prime Minister Wong Kan Seng said that Singapore has tightened security at its borders and checkpoints, following the killing of Al-Qaeda leader Osama bin Laden on Sunday.
He said at a press conference after a walkabout in Bishan-Toa Payoh constituency that some terrorist groups may be incited to take revenge for the killing and there is a need to put in place "appropriate measures".
Mr Wong added that Singaporeans have a tendency to take security for granted until "something happens in the neighbourhood, in the region". But as Singapore is an open economy, it must keep its ports and airports functioning while ensuring that citizens are not so paralysed by fear that they shut themselves off from the rest of the world.
The Ministry of Home Affairs has also released a statement to say 'it would be prudent for Singapore to be extra vigilant', in view of the recent activity by Jemaah Islamiah-related terrorist elements in Indonesia.
Large bombs were found in Indonesia on Good Friday, and grenades in Kuala Lumpur a couple of weeks ago.
