Malaysian Prime Minister Najib Razak condemned the “appalling” actions of Islamic State (IS) militants in Iraq and Syria in a statement Wednesday.

The statement comes after an outpouring of anger and grief around the world after the beheading of journalist James Foley by IS militants last week.

Najib joined other ASEAN state leaders, such as Indonesia’s Susilo Bambang Yodhoyono and Cambodia’s Hun Sen, in condemning the actions of the militants. Najib did not refer specifically to James Foley’s death in the statement.

“As reports of mass executions and killing of civilians surface, and graphic evidence of brutality emerges, we have been appalled,” the statement says.

It adds: “Malaysia strongly condemns the actions of the Islamic State militants in Syria and Iraq… We are deeply saddened by the crimes committed in the name of Islam, a religion of peace. We deplore those responsible, and call on the international community to act in concert to prevent further violence. We must fight extremism with moderation, and work to rebuild the bonds between communities shattered by war.”
