Here's a roundup of news trending across the nation and world today.

What to know now:

1. EgyptAir crash: An EgyptAir flight en route from Paris to Cairo crashed Thursday into the Mediterranean Sea with 66 passengers and crew members on board. Egyptian aviation officials are saying it's too early to determine whether the plane was shot  down in an act of terrorism or if a technical issue was the cause of the crash. "We cannot rule anything out," said Egyptian Prime Minister Sherif. The plane,  an Airbus A320, fell off the  radar at 2:45 a.m. Cairo time (8:45 p.m. EDT) when it was flying at 37,000 feet 175 miles north of the Egyptian coast, the airline said. Airbus confirmed in a statement the "loss of an EgyptAir A320."  One report says the captain of a merchant ship reported seeing a "flame in the sky" at about the time the plane disappeared from radar.

2. Donald trumps Hillary: A new national poll released by Fox News Wednesday shows Donald Trump defeating Hillary Clinton 45 percent to 42 percent in a general election. However, Trump's lead is within the poll's margin of error. Trump's strength comes in male voters where he beats Clinton 55-33 percent, and independents where he leads by 16 percent. Clinton leads Trump 90 percent to 7 percent among blacks.

3. Chinese fighters: A pair of Chinese fighter jets intercepted a U.S. spy plane over the South China Sea, the Pentagon said Wednesday. The jets made "unsafe" contact, Department of Defense spokesman Major Jamie Davis said in a statement. "The Department of Defense is reviewing a May 17 intercept of a US maritime patrol reconnaissance aircraft by two tactical aircraft from the People's Republic of China," Davis said. Tensions between the two countries have been high as China continues to construct military installations on islands in the South China Sea.

4. Mom convicted: Twenty-five years after a 5-year-old went missing, allegedly from a carnival, the boy's mother has been convicted of his murder. Michelle Lodzinski, 48, was found guilty of the murder of her son, Timothy Wiltsey. According to Lodzinski, Timothy disappeared as she went to buy a drink at a carnival she had taken him to. Timothy's body was found a year later in a marsh.

5. Still counting: The results from Kentucky's Democratic primary should be finalized by Thursday, according to officials there.
