Fight, Ceasefire, Repeat: US-Iran Conflict's Four-Month Timeline Of War And Truce

Last Updated:June 29, 2026, 08:34 IST

Since US and Israel launched strikes on Iran on February 28, the crisis has followed a familiar pattern - escalation, retaliation, diplomacy, ceasefire and renewed confrontation.

Just when it appeared that the United States and Iran had stepped back from the brink, fresh tensions once again exposed how fragile peace remains in West Asia. The latest ceasefire announcement, following Iran’s retaliatory strike on the Al Udeid air base in Qatar and renewed diplomatic efforts led by Doha, has offered temporary relief to a region that has spent months oscillating between open conflict and uneasy pauses.

But the current truce is far from the first. Since the US and Israel launched military strikes on Iran on February 28, the crisis has followed a familiar pattern – escalation, retaliation, diplomacy, ceasefire and then renewed confrontation. Even during periods officially described as ceasefires, attacks on shipping routes, proxy groups and military assets have continued to threaten regional stability.

Here’s a look at how the conflict has unfolded over the past four months.

February 28: Conflict Breaks Into the Open

The current phase of the US-Iran confrontation began when the United States, alongside Israel, launched coordinated strikes targeting Iranian military and strategic facilities.

Iran responded within hours, firing missiles and deploying drones against Israeli positions and US-linked targets across the region, marking one of the most direct military confrontations between the two sides in recent years.

March: Retaliation Expands Across the Region

As March progressed, Iran widened its response beyond Israel. American military installations in the Gulf increasingly came under attack, while Iranian-backed groups stepped up operations against US interests across West Asia. The Strait of Hormuz, one of the world’s busiest oil shipping routes, also emerged as a major flashpoint, raising fears of disruptions to global energy supplies.

With casualties mounting and regional tensions soaring, concerns grew that the conflict could spiral into a much larger regional war.

April 7-8: First Ceasefire Announcement

After weeks of sustained fighting, US President Donald Trump announced what he described as a two-week ceasefire. Iran later confirmed that mediation efforts had produced a temporary halt in large-scale hostilities. While major attacks subsided, neither side declared an end to military operations, leaving the ceasefire inherently fragile.

April 11-12: Direct Talks Fail to Deliver Lasting Peace

Officials from US and Iran met in Islamabad in an attempt to extend the ceasefire and establish a more durable framework for de-escalation.

Although both sides remained engaged diplomatically, the talks ended without a comprehensive agreement, leaving several core disputes unresolved.

Late April-Early May: Uneasy Calm Gives Way to Fresh Tensions

While large-scale fighting remained limited, tensions never fully disappeared. The United States intensified efforts to restrict Iranian maritime activity, while Tehran maintained pressure around the Strait of Hormuz through naval manoeuvres and indirect actions. Both sides accused each other of violating the spirit of the ceasefire.

May 4-11: Strait of Hormuz Becomes The Main Flashpoint

By early May, clashes around the strategically vital Strait of Hormuz once again tested the fragile truce. Following renewed incidents at sea, Trump temporarily paused a US maritime security mission as negotiations continued. However, repeated exchanges of fire and competing accusations of ceasefire violations prevented any meaningful breakthrough.

May 23-24: Hopes of a Deal Rise

Towards the end of May, Trump claimed that a broader peace agreement was close. US officials also indicated that both countries had agreed in principle to steps aimed at reopening the Strait of Hormuz to normal commercial shipping, a move viewed as critical for stabilising global oil markets.

Despite the optimism, a formal settlement remained elusive.

June 1-12: Negotiations Stall Again

Momentum quickly faded. Iran linked progress in talks to wider regional issues, including the conflict in Lebanon and broader security guarantees. At the same time, disagreements over navigation and military activity in the Strait of Hormuz resurfaced, slowing diplomatic progress.

June 14-18: Another Ceasefire Takes Shape

Fresh negotiations eventually produced another interim agreement. The new understanding extended the ceasefire for 60 days while also easing maritime restrictions by lifting the US naval blockade on Iranian commercial shipping.

The agreement was seen as the most significant diplomatic breakthrough since the conflict began.

June 20-23: Fighting Returns Before Another Pause

The calm proved short-lived. Fresh violations and retaliatory strikes once again threatened to derail the agreement. The most dramatic escalation came after Iran targeted US forces stationed at Al Udeid Air Base in Qatar.

Soon after, Trump announced another ceasefire, with Qatar playing a central role in facilitating renewed dialogue between Washington and Iran.

June 25: Truce Shows Signs of Strain

Barely days after the latest ceasefire announcement, reports emerged that Iran had struck a commercial vessel transiting the Strait of Hormuz.

The incident underscored a recurring reality throughout the conflict: ceasefires have reduced direct large-scale attacks but have not eliminated military pressure, proxy actions or risks to international shipping.

What Does The Pattern Say?

The US-Iran confrontation has evolved through three distinct phases – an intense period of direct military conflict, multiple temporary ceasefires and an ongoing cycle of negotiated truces punctuated by renewed violence.

Rather than bringing a decisive end to hostilities, each ceasefire has served as a pause that created space for diplomacy while leaving many of the underlying disputes unresolved.

With Qatar now preparing to host fresh talks focused on the Strait of Hormuz, all eyes are on whether the latest pause can evolve into something more durable. Yet the events of the past four months suggest that until the core strategic disagreements between Washington and Tehran are addressed, the region is likely to remain trapped in a cycle of fight, ceasefire and repeat.
