The brutal terrorist attacks in recent months, happening one after another, put people "at risk of becoming numbed", Prime Minister Lee Hsien Loong wrote in a Facebook post yesterday.
"Shocked to learn of the shootings in #Munich," he wrote.
"We have seen so many brutal terrorist attacks in recent months, one after another. We are at risk of becoming numbed, and have to remind ourselves of the terrible human tragedy each time," he added.
In a letter to German Chancellor Angela Merkel yesterday, Mr Lee said Singapore condemns the "senseless act" in Munich.
"I am deeply shocked by the tragic shooting in Munich... that has resulted in the loss of innocent lives and many injuries. We wish those injured a speedy recovery.
"I offer our deepest condolences to the bereaved families. We condemn this senseless act of violence. Our thoughts are with the people of Germany," he said.
Foreign Minister Vivian Balakrishnan also wrote on Facebook that he was "saddened by yet another vicious attack on innocents".
"Our thoughts and prayers go out to all those who have lost their loved ones to this attack," Dr Balakrishnan said.
The Ministry of Foreign Affairs (MFA) said it had verified the safety of all registered Singaporeans in Munich.
It also advised Singaporeans who are there to stay vigilant.
