While you were away: Catch up on the weekend's top stories

U.S. President Barack Obama waves to the audience after speaking at his final White House Correspondents' Association dinner.

(CNN)You had a busy weekend. So did the world.

President Obama did a mic drop. A U.S. cruise ship set sail for Cuba. Kenya's government burned more than 100 tons of ivory.
Not sure how to catch up with so much going on? Don't worry, we've got you covered.
    Here's a quick look at what happened around the world while you were away:

    Obama drops the mic

    Whether or not you're a fan of Obama, this much is clear: The man knows how to work a room. The U.S. President cracked up the crowd Saturday at his final White House Correspondents' Dinner.
    Standing center stage at Washington's annual opportunity to pretend it's hip, Obama didn't pull any punches, dishing out jokes about the media, his political rivals and his own future.
    "If this material works well," the President quipped, "I'm gonna use it at Goldman Sachs next year. Earn me some serious Tubmans."
    The warm reception he got at the dinner isn't the only thing Obama has to brag about. Sunday, the White House announced that Malia, his oldest daughter, is heading to Harvard in 2017.

    Birthday princess

    Speaking of daughters in the spotlight, Britain's Princess Charlotte posed for a new series of photos released ahead of her first birthday.
    And she wasn't the only member of the royal family smiling for the camera.
    Her mother, the Duchess of Cambridge, will be on the cover of the 100th issue of British Vogue next month.

    Más salsa, por favor

    The first U.S. cruise ship heading to Cuba in decades arrives in Havana on Monday for the first stop of its seven-day voyage.
    Wish you were sipping mojitos and salsa dancing onboard? We understand; somehow our tickets also seem to have gotten lost in the mail.
    Luckily, CNN's Annie Rose Ramos is bringing us with her on the journey, introducing people she's meeting along the way.

    May Day protests

    On the internet, May 1 means you'll be seeing memes of Justin Timberlake in all his 90s glory.
    In Seattle, it means there's probably a protest.
    The city held rallies and protests for May Day -- which is observed in many countries around the world as International Workers' Day -- and like last year, it ended in violence.
    Nine people were arrested and five cops were hurt, Seattle police said.

    Drugs in the heartland

    It's been more than a week since eight people from a single family were found slain across the tight-knit town of Piketon, Ohio. And if investigators are any closer to figuring out who was behind the killings, they're not saying.

    Authorities haven't revealed whether the hundreds of illegal marijuana plants found on properties tied to the family had anything to do with the deaths. But no matter what, CNN's Emanuella Grinberg reports, the high-profile case is casting a spotlight on the remote region's ties to the drug trade.

    Ransacking parliament

    Throngs of protesters rushed into Baghdad's Green Zone on Saturday. It was a startling sight in an area that's normally off limits and packed with government buildings and foreign embassies. Angry after lawmakers failed to replace some cabinet members, the protesters broke into Parliament, ransacked rooms and sat at lawmakers' desks while gesturing at cameras that captured the scene.

    The protests are the latest twist in a political crisis that's made it difficult for the country to battle ISIS.
    While politicians spar, the terrorist group is still pushing forward. ISIS claimed responsibility for a pair of suicide bombings that killed at least 11 people in southern Iraq on Sunday.

    Up in smoke

    Thick plumes of ash and smoke billowed over a Kenyan national park Saturday as the government burned more than 100 tons of elephant and rhino tusks. It was the strongest stand against poaching in the region and the largest burn of illegal wildlife products in history.
    The tusks would be worth more than $105 million on the black market, one expert told CNN. But Kenyan officials say the ivory only has value when it's a tusk on a live elephant.
    "From a Kenyan perspective," Kenya Wildlife Service Director General Kitili Mbathi said, "we're not watching any money go up in smoke."

    Leaving the ring

    A group of elephants from the Ringling Bros. and Barnum & Bailey circus have a happier future in front of them: retirement.
    After years of giant tricks and synchronized dances, six Asian elephants entered the ring in Providence, Rhode Island, on Sunday and performed their final act.
    This follows years of protest about the conditions the elephants -- and other animals -- endure when they're used in shows for human entertainment.
    But when it comes to retirement, it turns out elephants are just like the rest of us. They're heading to a sanctuary in Florida.
