Guterres "calls on all the parties to the current conflict in the Middle East to comply with their obligations under international law and to abide by the terms of the ceasefire in order to pave the way toward a lasting and comprehensive peace in the region," Dujarric said in a statement, Anadolu Agency reported.
The statement came after US President Donald Trump on Tuesday accepted Iran's demands and announced that he agreed "to suspend the bombing and attack of Iran for a period of two weeks."
Guterres emphasized that an immediate end to hostilities is critical to protecting civilian lives and alleviating human suffering amid the ongoing crisis.
He also expressed appreciation for the mediation efforts led by Pakistan and other nations working to facilitate the ceasefire agreement, according to Dujarric.
"The Secretary General’s Personal Envoy Jean Arnault is in the region to support efforts toward lasting peace," he added.
