Iran’s Supreme National Security Council said Tuesday it has accepted a two-week ceasefire in the war and that it plans to negotiate with the United States in Islamabad beginning Friday.

“It is emphasized that this does not signify the termination of the war,” the statement said. “Our hands remain upon the trigger, and should the slightest error be committed by the enemy, it shall be met with full force.”

US President Donald Trump said he’s pulling back on his threats to widen attacks on Iran -- targeting an array of bridges, power plants, and other civilian targets, subject to Iran being ready for a two-week ceasefire and to reopen the Strait of Hormuz.

He said Iran has proposed a “workable” 10-point peace plan that could help end the war launched by the US and Israel in February.

Trump’s latest threat over the Iran war hit a new extreme earlier Tuesday when he warned, “A whole civilization will die tonight, never to be brought back again,” if Iran fails to make a deal that includes reopening the vital Strait of Hormuz.

The Republican president’s earlier comments were swiftly met with condemnation from Democrats, some “Make America Great Again” supporters who have since broken with Trump, and the first American pope.

Meanwhile, an Israeli military official, who spoke on condition of anonymity in line with regulations, said early Wednesday that Israel was still attacking Iran. Iran also kept up the fire on Israel.
