The Khobar Towers bombing was a terrorist attack on part of a housing complex in the city of Khobar, Saudi Arabia, near the national oil company (Saudi Aramco) headquarters of Dhahran and nearby King Abdulaziz Air Base on 25 June 1996. At that time, Khobar Towers was being used as living quarters for coalition forces who were assigned to Operation Southern Watch, a no-fly zone operation in southern Iraq, as part of the Iraqi no-fly zones.

A truck bomb was detonated adjacent to Building #131, an eight-story structure housing members of the United States Air Force's 4404th Wing (Provisional), primarily from a deployed rescue squadron and deployed fighter squadron. In all, 19 U.S. Air Force personnel were killed and 498 of many nationalities were wounded. The official 25 June 1996, statement by the United States named members of Hezbollah Al-Hejaz (English: 'Party of God in the Hijaz') as responsible. In 2006, a U.S. court found Iran and Hezbollah guilty of orchestrating the attack. In July 2020, a US court ordered Iran to pay $879m to the Khobar bombing survivors.

Alexandria is an independent city in the Commonwealth of Virginia in the United States. As of 2020, the population was 159,467. The city's estimated population has grown by 1% percent annually since 2010 on average. Located along the western bank of the Potomac River, Alexandria is approximately 7 miles (11 km) south of downtown Washington, D.C.

Like the rest of Northern Virginia, as well as Central Maryland, modern Alexandria has been influenced by its proximity to the U.S. capital. It is largely populated by professionals working in the federal civil service, in the U.S. military, or for one of the many private companies which contract to provide services to the federal government. One of Alexandria's largest employers is the U.S. Department of Defense. Another is the Institute for Defense Analyses. In 2005, the United States Patent and Trademark Office moved to Alexandria, and in 2017, so did the headquarters of the National Science Foundation.

The historic center of Alexandria is known as Old Town. With its concentration of boutiques, restaurants, antique shops and theaters, it is a major draw for all who live in Alexandria as well for visitors. Like Old Town, many Alexandria neighborhoods are compact and walkable. It is the 7th largest and highest-income independent city in Virginia.

A large portion of adjacent Fairfax County, mostly south but also west of the city, has Alexandria mailing addresses. However, this area is under the jurisdiction of Fairfax County's government and separate from the independent city. The city is therefore sometimes referred to as the "City of Alexandria" to avoid confusion (see the "Neighborhoods" paragraph below). Additionally, neighboring Arlington County was formerly named "Alexandria County" before it was renamed by the Virginia General Assembly in 1920 to reduce confusion with the city.
