Donald Trump has said the US will begin blockading the strait of Hormuz in an attempt to take control of the strategic waterway from Iran in the aftermath of failed peace negotiations between the countries in Pakistan.

The US president also threatened to bomb Iran’s water treatment facilities, power plants and bridges if Tehran did not agree to abandon its nuclear weapons programme, the key sticking point between the two sides.

Israel has carried out its largest attack on Lebanon since its war with Hezbollah began, killing at least 254 people and wounding 837, an assault that prompted Iranian officials to warn Tehran could withdraw from the ceasefire agreed with the US overnight.

Warplanes levelled several buildings in the centre of Beirut, filling the skies with smoke in what Israel’s defence minister said was “a surprise strike” on the pro-Iranian group Hezbollah.

Donald Trump has warned that Iran’s “whole civilisation will die tonight” if Tehran did not comply with his demands, as the world braced to see if the president would deliver on his latest threat to order the mass destruction of Iranian power plants and bridges in the absence of a deal by 8pm EDT (1am BST).

Iran’s Revolutionary Guards signalled they were also ready to escalate the war with a threat to retaliate “beyond the region” and “to deprive the US and its allies of oil and gas in the region for years”, suggesting Iran would target oil and gas production facilities in the Gulf and elsewhere, potentially sending the world into a recession.

Diplomatic negotiations aimed at halting the war in the Middle East appeared to be faltering a day before a deadline imposed by Donald Trump with a threat to destroy Iran’s bridges and attack its power plants.

Mediators from Pakistan, Egypt and Turkey want both sides to agree to a ceasefire and reopen the strait of Hormuz, to be followed by a period of detailed negotiations intended to reach a more complete peace agreement.

Donald Trump issued an expletive-laden warning on Sunday that Tehran had until Tuesday night to reopen the strait of Hormuz or the US would obliterate Iran’s power plants and bridges.

Iran’s parliament speaker responded with a warning that the US president’s “reckless moves” would mean “our whole region is going to burn”.

Donald Trump will claim rescue as a triumph but 48-hour drama should be a caution against launching ground operation

• Middle East crisis – live updates

Donald Trump will inevitably claim the rescue of the second crew member of the downed F-15 fighter as a propaganda triumph, though the 48-hour drama is a reminder that an undefeated Iran is able to fight back and inflict costs on the US.

It also ought to be a caution for a White House still contemplating whether to launch a ground operation in Iran to seize an island in the Persian Gulf – particularly if there a serious ambition to extract Iran’s highly enriched uranium from deep underground.

The second crew member of a downed F-15E fighter jet has been rescued by US commandos overnight, ending a two-day search after the warplane crashed in south-west Iran.

One US service member has been rescued after a US F-15E Strike Eagle fighter was shot down over Iran, prompting a frantic effort to locate its two-strong crew, in the first such incident since the war began almost five weeks ago.

US officials familiar with the situation said one crew member was still missing late on Friday, after Iranian state media released images of a tail fin and other debris accompanied by an initial claim that an advanced US F-35 had been hit by a new air defence system over central Iran.

Donald Trump claimed responsibility for destroying Iran’s largest bridge, a day after he threatened to bomb the country “back to the stone ages” if a deal to end the five-week-long war he started was not reached.

The US president shared footage of part of the newly built 136 metre-high $400m B1 suspension bridge between Tehran and Karaj collapsing dramatically on to the causeway below amid a rising plume of black smoke.
