In 1984, an 11-day police siege began at Libya's embassy in London when an unidentified shooter inside the building fired on a crowd of protesters, killing police officer Yvonne Fletcher. (The Libyans in the embassy were eventually allowed to leave the country as Britain and Libya severed relations.)

In 1986, at London's Heathrow Airport, a bomb was discovered in the bag of a pregnant Irishwoman about to board an El Al jetliner to Israel; she'd been tricked into carrying the bomb by her Jordanian fiance.

Five years ago: A day after U.N. inspectors left North Korea, U.S. experts monitoring the communist country's nuclear program also departed after Pyongyang expelled them and threatened to restart its reactor in anger over U.N. criticism of its recent rocket launch.

One year ago: Fifteen people were killed by a fertilizer plant explosion in West, Texas. Sports returned to Boston two days after the deadly Marathon bombing as the Buffalo Sabres defeated the Bruins in a 3-2 shootout (players on both teams wore "Boston Strong" decals on their helmets). Senate Republicans backed by a small band of rural-state Democrats scuttled the most far-reaching gun control legislation in two decades. Senate Finance Committee Chairman Max Baucus, D-Mont., who'd helped write President Barack Obama's health care law, stunned administration officials during a budget hearing by saying he thought it was headed for a "train wreck" because of bumbling implementation. A Mississippi man was arrested, accused of sending letters to President Barack Obama and a senator that tested positive for poisonous ricin (however, charges against Paul Kevin Curtis were later dropped and leveled against James Everett Dutschke instead; prosecutors said Dutschke, who ended up pleading guilty to sending the letters, had tried to frame Curtis).
