Benjamin Netanyahu has declared that Israel's campaign against the Islamic Regime is 'not over' as US-Iran peace talks are underway in Pakistan. 

Speaking in a televised address on Saturday, the Israeli Prime Minister also said 'we still have more to do' to ensure Iran doesn't achieve a nuclear weapon. 

'But we can already say clearly - we have historic achievements,' he affirmed. 

'They wanted to strangle us, and (now) we are strangling them. They threatened us with annihilation, and now they are fighting for survival,' Netanyahu added, as he noted that the war against Tehran had also weakened Iran's leadership and its regional allies. 

Netanyahu's remarks came as US and Iranian negotiators held talks in Pakistan on Saturday to try to end their six-week war. 

The talks in Islamabad were the first direct US-Iranian meeting in more than a decade and the highest-level discussions since the 1979 Islamic Revolution.

The Strait of Hormuz, a major transit point for global energy supplies that Iran has effectively blocked but Trump has vowed to reopen, is crucial to negotiations between the sides during a two-week ceasefire agreed last week.

Iran's semi-official Tasnim news agency said the waterway remains among the main points of 'serious disagreement' in talks between Iranian and US delegations in Islamabad.

The American military said two of its warships had passed through the strait, and conditions were being set to clear mines, while Iran's state media denied any US ships had transited the waterway.

'We're now starting the process of clearing out the Strait of Hormuz as a favour to Countries all over the World,' Trump posted on social media.

US Vice President JD Vance, special envoy Steve Witkoff and Trump's son-in-law Jared Kushner flew in on Saturday and met Iranian Parliamentary Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi for two hours before resting, according to a source from the mediator, Pakistan. 

The Iranian delegation arrived on Friday dressed in black in mourning for former Supreme Leader Ayatollah Ali Khamenei and others killed in the war. 

They carried shoes and bags of some students killed during the US bombing of a school next to a military compound, the Iranian government said.

Iran's state-affiliated Nournews said talks would resume later on Saturday night or Sunday.

US ally Israel, which joined the February 28 attacks on Iran that launched the war, has also been bombing Tehran-backed Hezbollah militants in Lebanon and says that the conflict is not part of the Iran-US ceasefire.

Israeli and Lebanese officials plan talks in the US on Tuesday. 

In his televised address today, Netanyahu also said that any peace agreement reached with Lebanon must be the one that 'lasts for generations'.
