Iran is still examining the final version of a potential agreement with the US and has not yet replied, according to a source cited by the semi-official Mehr news agency.

Iran is seeking to achieve "real, tangible" benefits, the source added, saying that "the history of US non-compliance and historical distrust" has led Tehran to view the issue "very strictly," The Caspian Post reports, citing Anadolu Agency.

Tensions in the Middle East have escalated since the US and Israel launched strikes on Iran in February. Tehran retaliated with attacks targeting Israel and US allies in the Gulf, alongside the closure of the Strait of Hormuz.

A ceasefire took effect on April 8 through Pakistani mediation, but subsequent talks in Islamabad failed to produce a lasting agreement. Efforts for a solution, however, have continued since.

One of Iran’s conditions to end the war permanently is the end of fighting on all fronts, including in Lebanon, where the latest Israeli assault continues since early March.

US President Donald Trump on Monday said he asked Israeli Prime Minister Benjamin Netanyahu to pull back his troops from Beirut.
