The ceasefire between the United States (US) and Iran has been dealt several blows in the past week by both sides as the conflict has intensified again, plunging the region into fresh turmoil.Last month, Washington and Tehran had agreed to a Memorandum of Understanding (MoU) brokered by Pakistan, Qatar, and other regional countries. The US officials had read out the 14-point document in June, which dealt with the reopening of the Strait of Hormuz, easing financial strain on Iran, and set out a plan on addressing and discussing Tehran’s nuclear programme, among others.On Sunday, the US military launched a fresh round of strikes after two of its soldiers were killed in Jordan in Tehran’s attacks. The latest US strikes targeted Iran’s under-construction Darkhovin nuclear power plant in the country’s southwest region.
