LIVE: Iranian Delegation in Pakistan for Talks with US

US Vice President JD Vance warned Iran meanwhile not to try to "play" Washington as he headed to Islamabad to represent the United States.

Despite the temporary truce struck between the foes, deep disagreements remain as to the way forward in talks aimed at transforming the fragile ceasefire into a lasting peace deal.

Pakistani Prime Minister Shehbaz Sharif said making progress would be hard work.

"A temporary ceasefire has been announced, but now an even more difficult stage lies ahead: the stage of achieving a lasting ceasefire, of resolving complicated issues through negotiations," he said.

"This is that stage which, in English, is called the equivalent of 'make or break.

'" Iranian state television said the delegation was led by parliamentary speaker Mohammad Bagher Ghalibaf and reiterated Iran's position that talks would only begin if Washington accepts its preconditions -- a Lebanon ceasefire and the unfreezing of Iran's assets.

Israel continued to carry out air strikes in Lebanon on Friday and Lebanon's State Security agency said an attack on the southern city of Nabatiyeh had killed 13 of its personnel.

Lebanon's health ministry meanwhile raised the provisional death toll from massive Israeli strikes across the country on Wednesday to 357 dead and 1,223 wounded.
