An Iranian minister has told the BBC that Israeli strikes in Lebanon on Wednesday constituted a grave violation of the US-Iran ceasefire agreement.
Deputy Foreign Minister Saeed Khatibzadeh said Lebanon was covered by the two-week deal agreed on Tuesday - something the US and Israel dispute - and said the US must choose between war and ceasefire.
The Lebanese health ministry has said at least 203 people were killed on Wednesday in air strikes on what Israel called Hezbollah command centres and military sites.
Pressed on whether Tehran would likewise ask Hezbollah to stop firing rockets towards Israel, Khatibzadeh claimed the Iranian-backed militant group had abided by the ceasefire.
Hezbollah said on Thursday that it had fired at Israel overnight in response to what it called ceasefire violations.
It has also threatened to keep up its attacks until Israeli-American aggression against Lebanon comes to an end.
Speaking to BBC Radio 4's Today programme, Khatibzadeh said Tehran had sent a crystal clear message to the White House late on Wednesday which could be summarised as you cannot have cake and eat it at the same time.
He elaborated, You cannot ask for a ceasefire and then accept terms and conditions, accept all the areas that a ceasefire is applied to, and name Lebanon, exactly Lebanon in that, and then your ally just starts a massacre.
He said the deal that was reached - which Trump called a workable framework - meant Iran, Washington and each of their allies were to adhere to the ceasefire, and claimed Hezbollah had very much abided by that.
Khatibzadeh also addressed Tehran's warnings regarding ships passing through the Strait of Hormuz without permission, asserting that Iran would comply with international law, provided the US ceased its aggression.
The reverberations of these escalations have been felt globally, affecting international economic stability, particularly in the critical Strait of Hormuz, which is a vital route for oil transport.
