Sajida al-Rishawi was one of two al Qaeda prisoners executed by Syria

(CNN)Jordan executes two al Qaeda prisoners in retaliation. A New York train collision kills seven. And a "To Kill a Mockingbird" sequel is on the way.

It's Wednesday, and here are the 5 Things to Know for Your New Day:

ISIS OUTRAGE

In retaliation: Jordan executed two al Qaeda prisoners before dawn today, following through on a promised strong response to ISIS' killing of pilot Moath al-Kasasbeh. Put to death were Sajida al-Rishawi, a would-be iraqi suicide bomber, and Ziad Karbouli, a former top aide to the deceased leader of al Qaeda in Iraq. The executions come a day after video and stills appeared to show the Jordanian military pilot being burned alive while confined in a cage. Jordanians took to the streets to protest the brutal killing, demanding a government response.

    TRAIN COLLISION

    Stuck on the tracks: A packed Metro North commuter train plowed into a Jeep Cherokee on the tracks north of New York City yesterday, bursting into flames and killing at least seven people. Six of those killed were on board the train. The seventh fatality was the driver of the Jeep. The woman driving the SUV got stuck on the tracks when the crossing gates came down. The train was filled with more than 600 people at the time of the collision.

    VACCINES

    The unvaccinated: With the measles outbreak across the U.S., many are asking: Who are these parents that aren't bringing their kids in for vaccinations? First of all, it's a relatively small group. The CDC says 95% of children in kindergarten have had vaccines for preventable diseases. Nearly all states allow religious exemptions. A smaller number let folks opt out for philosophical reasons. Many parents of unvaccinated children say they're concerned about side effects, autism and children having too many shots as they're growing up. Doctors say they're myths.

    BOBBI KRISTINA

    New hospital: Bobbi Kristina Brown is now being treated at Atlanta's Emory University Hospital after being found facedown in a bathtub of water over the weekend. The daughter of singers Bobby Brown and Whitney Houston remains in a fight for her life. Her family has been tight-lipped on the 21-year-old's condition, but at last report she was on a ventilator in the intensive care unit. The family's lawyer threw out this tidbit last night: "We are currently investigating the events that led to the hospitalization of Bobbi Kristina." What does that mean? We're not sure, but police haven't said anything yet that points to foul play.

    HARPER LEE

    What took so long?: Fifty-five years is a long time to wait for a sequel, but we'll be getting one later this year for "To Kill a Mockingbird." It's called "Go Set a Watchman," and follows Scout, the little girl from "Mockingbird," as an adult. Harper Lee's classic novel came out in 1960 and was destined to be her only literary work until the manuscript for "Watchman" was rediscovered last year, the 88-year-old Lee said in a statement from her publisher. The new book was actually written before "Mockingbird," but was set aside at the advice of her editor. Mark your calendars for July 14 if you're interested.
