They found 75 bomb detonators in a dump

A Muslim militant group is blamed for suicide bombings that rippled across Sri Lanka on Sunday, killing 290 people including some Americans at Easter church services and elsewhere. The local group, National Thowfeek Jamaath, supplied all seven bombers for the attacks, government officials said Monday. Police found more bombs, too, inside a van that exploded Monday (without injuries) after police tried to defuse them. At least 24 people were in custody for questioning in the attacks. Sri Lankan officials said there were indications that an attack would occur, and warnings were issued as early as April 4.

Dieter Kowalski, 40, of Colorado was among at least four Americans killed in the bombings, his employer confirmed. Sri Lanka, an island nation off India of 22.5 million people, is home to several factions that have jostled for power.

What else we know:

  • A Danish billionaire lost three of his four children in the attacks.

  • Officials say they found 75 bomb detonators in a garbage dump outside Colombo, one of the attacked cities.

  • Authorities blocked most social media after the attacks, possibly fearing inflammatory content could provoke more violence.

A 99.9999% chance it's our fault

Happy Earth Day! A study reached “hand-sanitizer-guarantee” levels of certainty that humans affect climate change: There's a 99.9999% chance that humans are the cause of global warming. The Earth has experienced 42 straight years with an above-average global temperature, according to the National Oceanic and Atmospheric Administration. Extreme weather events – such as Hurricane Michael and the wildfires that scorched California last year – killed almost 250 Americans and cost the nation at least $91 billion in 2018.

Judge to MLB star: Pay your mistress

The secret children of MLB star Miguel Cabrera and his ex-mistress hit a grand slam, legally speaking. After being kept in the dark for the past five years, Cabrera’s two kids fathered with his Florida mistress, Belkis Rodriguez, are legally entitled to the same lifestyle and opportunities enjoyed by the children from his marriage, a judge ruled. Along with $20,000 a month to each child, child support back pay and other payments, the Tigers slugger will have to provide the kids annual passes to Walt Disney World, Universal Studios, Sea World and Orlando Science Center.

More Americans than ever are leaving the Catholic church

As millions filled Catholic pews for Easter, others hovered at the door over the church’s handling of a decades-long crisis involving young children abused by priests who were often protected by superiors. Seven months after a damning report revealed 1,000 children were abused by more than 300 priests in Pennsylvania, a Gallup poll in March found 37% of U.S. Catholics are considering leaving the church because of the sex abuse crisis and the church’s response. The USA TODAY Network sent 13 reporters to parishes across the country to talk with dozens of Catholics about the scandal. “I don’t know why I still go," said Barbara Hoover, 73, a retiree in York, Pennsylvania. I guess the ritual.”

Can you be fired because you're LGBTQ?

That's the question at the heart of discrimination challenges the Supreme Court agreed to hear Monday. The justices will hear three cases from New York, Michigan and Georgia involving workers who claim they were fired because they are gay or transgender. This will be the first stress test for LGBTQ rights at the Supreme Court since Brett Kavanaugh was confirmed this year, tipping the nine-justice balance toward a more conservative majority.
