Given the deeply rooted differences, an agreement cannot be reached overnight.

Axar.az reports that United Nations Secretary-General Antonio Guterres called on the talks between United States and Iran to continue constructively for an agreement to be reached.

“While no agreement was reached at the talks hosted by Pakistan between the United States and the Islamic Republic of Iran in Islamabad, the discussions themselves underscored the seriousness of their engagement and constituted a positive and meaningful step toward renewed dialogue,” the statement read.

"The ceasefire must absolutely be preserved and that all violations must cease," Guterres stressed.

UN Secretary-General thanked the continued efforts of the mediators – Pakistan, which hosted these talks, as well as Saudi Arabia, Egypt and Turkiye – and calls for the international community to support those efforts.

The first round of talks between the two sides was held in Islamabad on April 11, while a new round is expected on April 16.
