The statement came a day after Washington and Tehran agreed to a two-week ceasefire brokered by Pakistan, which halted six weeks of fighting.

The U.S. military said it hit more than 13,000 targets in its 38-day war with Iran, before the leaders of both countries announced a ceasefire on April 7, hours after President Donald Trump threatened that Iran's "whole civilization will die tonight."

Trump threatened that the U.S. will ‌start "shooting" again unless Tehran fully complies with the deal reached with Washington.

The U.S. military has launched strikes on Iran's Kharg Island ahead of President Trump's deadline for the country to reopen the Strait of Hormuz.

The US president has accused Iran of "doing a very poor job" with the waterway and said Tehran "better not be" charging fees to oil tankers.
