SINGAPORE - The Ministry of Foreign Affairs (MFA) has condemned the Islamic State in Iraq and Syria (ISIS)'s "repeated brutality", in the wake of American aid worker Peter Kassig's execution on Sunday.
The American aid worker, also known as Abdul-Rahman Kassig, was executed with 18 men described as Syrian military personnel, according to the video released by ISIS.
"We extend our deepest condolences to the family and friends of Mr Kassig, and reiterate our call for all hostages held by ISIS to be released immediately," a MFA spokesman said.
"This latest incident reinforces the urgent need for the international community to work together to counter the threat posed by ISIS and other terrorist groups.
"We need a comprehensive strategy to contain and weaken ISIS, and tackle the roots of extremism. As a member of the multinational coalition against ISIS, Singapore will do our part to combat this terrorist scourge."
