US-Iran tensions escalated after fresh military strikes and retaliatory claims by Iran’s IRGC, putting the fragile ceasefire at risk and raising new concerns over security in the strategically vital Strait of Hormuz.

US-Israel-Iran War Latest News: Trump Warns of Response as Iran Rejects Ceasefire Violation Claims
US-Israel-Iran War Latest News: The fragile ceasefire between the United States and Iran came under fresh strain late Friday and early Saturday after Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy claimed it had targeted US military positions in response to recent American airstrikes on Iranian coastal sites.
The reported retaliation has raised fresh concerns that the truce agreed just days ago could begin to collapse, increasing the risk of renewed conflict in the strategically important Strait of Hormuz.
US-Israel-Iran War Latest News: What Triggered the Latest Escalation?
The latest round of tensions began after a drone attack targeted a cargo ship travelling through the Strait of Hormuz on Thursday. The United States blamed Iran for violating the ceasefire and warned that it was considering a military response.
When asked whether Washington would retaliate, US President Donald Trump told reporters, “You’ll find out.”
A few hours later, the US military carried out strikes on what it described as missile launch sites, drone facilities and coastal radar installations in Iran. The operation was later confirmed by US Central Command.
Speaking at the White House before the strikes, Trump said, “I don’t like the fact that they took a shot yesterday, actually four of them.” When questioned about taking military action despite earlier suggesting that negotiations with Tehran were progressing well, Trump replied, “They’re a little bit different.”
The operation represents the biggest challenge yet to the interim agreement reached just one week ago. Under the deal, both countries had agreed to begin reducing hostilities and work toward restoring stability in one of the world’s busiest shipping routes.
US-Israel-Iran War Latest News: Iran Denies Breaking the Ceasefire
Iran rejected the US accusation that the drone attack violated the ceasefire. Ebrahim Azizi, head of the Iranian parliament’s national security commission, defended Tehran’s position and said Iran has the authority to regulate activities in the Strait of Hormuz. “The Strait of Hormuz is governed by Iran, so: Respect the rules,” Azizi wrote on social media. He also urged others to “not mistake control for escalation.” According to Azizi, “This is not a violation of the ceasefire; it is ceasefire management.”
US-Israel-Iran War Latest News: US Calls for Diplomacy but Issues Warning
US Vice President JD Vance urged Iran to resolve disagreements through diplomatic channels instead of military action. At the same time, he warned that Washington would respond strongly to any future attacks. “But violence will be met with violence,” Vance said, while encouraging Iran to “pick up the phone” if disputes arise over the ceasefire agreement.
US and Iran Set Up Direct Communication Channel
Despite the renewed tensions, both countries have established a direct communication channel to prevent incidents in the Strait of Hormuz from turning into a broader military confrontation.
According to Iran’s state news agency Press TV, the communication mechanism was created after diplomatic talks held in Zurich last week. The arrangement is part of the final statement issued by mediators and is intended to reduce misunderstandings while helping implement the Islamabad memorandum of understanding.
US-Israel-Iran War Latest News: Iran Reaffirms Navigation Rules in the Strait
Iran has continued to insist that all ships travelling through the Strait of Hormuz must follow routes approved by Tehran. Deputy Foreign Minister Kazem Gharibabadi repeated that position on Friday.
“Safe passage through the Strait of Hormuz cannot be guaranteed under ambiguous arrangements, parallel routes or decision-making that does not take Iran’s role as a coastal state into account,” he said. He also warned that Iran could suspend alternative transit routes if vessels fail to coordinate with Iranian authorities before entering the waterway.
US-Israel-Iran War Latest News: Why the Strait of Hormuz Is Important
The Strait of Hormuz is one of the world’s most important maritime chokepoints, carrying a significant share of global oil and energy shipments. The current ceasefire is based on a 14-point interim agreement signed on June 18, which ended fighting triggered by earlier US-Israeli strikes on Iran and allowed shipping activity to gradually recover.
According to the Associated Press, 78 ships passed through the strait on Wednesday, the highest daily traffic since the conflict began. However, that remains well below the normal average of more than 130 vessels per day before the fighting started.
US-Israel-Iran War Latest News: Shipping Continues Despite Rising Tensions
The dispute over navigation rules has already affected maritime traffic. Reports said at least two oil tankers turned back after attempting to use a UN-backed transit route near Oman because Iran insisted that vessels travel only through shipping corridors approved by Tehran.
Despite Thursday’s drone attack and the latest exchange of strikes, more than two dozen commercial ships continued using the southern route through the Strait of Hormuz on Friday. However, growing military tensions continue to raise concerns about the safety of one of the world’s most critical trade and energy routes.
