1. Major Middle East Conflict Erupts: US-Israel Strikes on Iran

One of the most consequential stories of Week 9 was the dramatic escalation of hostilities in the Middle East. On 28 February 2026, the United States and Israel launched coordinated military strikes deep inside Iran, targeting key military sites and leadership as part of a broader operation to degrade Tehran’s strategic capabilities.(Reuters)

The offensive, described by Israeli officials as “pre-emptive,” marked a major turning point in longstanding tensions over Iran’s nuclear and missile programs. Tehran responded with an intense barrage of missiles and drones targeting Israeli cities and U.S. bases in several Gulf states, including the United Arab Emirates, Qatar, and Bahrain, leading to widespread infrastructure damage and civilian casualties.(The Guardian)

The conflict triggered global protests, with demonstrators taking to the streets in countries such as Turkey and Yemen to condemn the strikes, and opened a new chapter in regional tensions with implications for energy markets and international stability.(Reuters)

 2. Iran’s Supreme Leader Assassination Reported

Amid the military offensive, Iranian Supreme Leader Ayatollah Ali Khamenei was reportedly killed in the strikes, a development confirmed by state sources and reported by multiple outlets.

While proponents argue it could boost economic growth and strengthen resilience amid global competition, critics within France and other EU states decried the move as bypassing democratic processes and potentially undermining environmental and labor standards.
