Good morning.

U.S. President Donald Trump ordered military strikes on three nuclear sites in Iran on the weekend, inserting the country into the war between Israel and Iran and raising fears the attacks could lead to an escalation across the Middle East. Our full coverage is below, along with other key stories of the week.

The latest

• The surprise attack, dubbed Operation Midnight Hammer, involved decoys and deception and hit key nuclear enrichment sites at Fordow, Natanz and Isfahan.
• In an address to the nation on Saturday night, Trump said the sites were “totally obliterated” and warned “there will be either peace, or there will be tragedy for Iran.”
• White House officials meanwhile said that while it will take some time to know the extent of the destruction, initial assessments indicate the damage to three sites was severe and would set back Iran’s nuclear program “many years.”
• Iran fired at Israel today and warned the U.S. it will retaliate. Its Foreign Minister expressed outrage and said the country has a right to self-defence and the “door to diplomacy” is closed.
• U.S. Defence Secretary Pete Hegseth said the mission was not about forcing a regime change, a position Trump later seemed to contradict in a post on Truth Social.
• Airlines have cancelled flights to and from Dubai and Doha and are avoiding large parts of the Middle East.
• Oil prices could increase, and uncertainty rippling through global markets could push investors into buying dollars and other safe-haven assets.

The reaction

• Prime Minister Mark Carney and Foreign Affairs Minister Anita Anand issued statements condemning Iran’s nuclear ambitions and backing Washington. They are in Europe for defence talks - today with the European Union and tomorrow and Wednesday with NATO - and both meetings have been upended by the unprecedented U.S. bombings.
• Ottawa has advised Canadians in Iran to leave the country if they can safely do so or stay near bomb shelters. Since the conflict between Israel and Iran escalated earlier this month, Ottawa has been helping Canadians there find seats on commercial flights to Canada after they cross land borders into neighbouring countries.
• Even before the bombings, Iranians were already living in fear as their country exchanged missile attacks with Israel. But some are also hoping this could mark the end of an oppressive regime.
• Ukraine’s troops are bracing for a Russian assault, while also concerned the war in the Middle East will turn attention away from their conflict.

The Globe’s analysis

• Trump has initiated a three-front war, writes David Shribman. One in the Middle East, one within his Republican coalition and one against Democratic skeptics.
• Regime change in Iran would lead to chaos, Dennis Horak writes.
• A look at the B-2 stealth bomber used in the U.S. attack.
• On today’s Decibel, Doug Saunders breaks down the U.S.’s involvement in the Israel-Iran war and the political fallout in the Middle East.

The latest: Today marks the 40th anniversary of the Air India bombing. Annual events are planned in major cities, but this year, many relatives of the deceased are travelling to Ireland, near the crash site over the Atlantic Ocean, off the Irish coast.

The issue: All 329 people on board - most of them Canadians - were killed. The bombing is considered Canada’s worst terrorist attack but one that is hardly remembered by the general public. That stands in contrast to Cork, Ireland, where the naval base became the centre of the recovery mission. There, school children are still taught about the tragedy and every year the county holds a service at the permanent memorial overlooking the ocean. The lack of recognition, and a bungled RCMP investigation, has left bitterness in the victims’ loved ones in Canada.

Nisha Thampi’s mother was on Flight 182. The Ottawa-based physician said Canadians must not distance ourselves from the historic act of homegrown terror.
