The Manchester Arena was packed on Monday night with pop fans eager to hear Ariana Grande perform. Her songs are bubblegum pop, so picture the crowd: kids and their parents, teenagers with their friends, fans looking for a cheerful night out.

At the end of the concert, an explosion struck near the arena. The blast killed at least 22 people and injured more than 50.

In the first of three matches with the world's No. 1 Go player, a Google artificial intelligence program claimed victory Tuesday. It won the round by just a fraction of a point in Wuzhen, China, but the win was enough to leave its grandmaster opponent impressed and thoroughly confounded by the result.

Justice Department ethics experts have decided Robert Mueller can proceed as the special counsel leading the investigation into the Russian government's efforts to interfere in the 2016 election, despite his former law firm's representing President Trump's daughter Ivanka and son-in-law Jared Kushner.

"Peace is a choice we must make each day," President Trump said during a visit to the West Bank city of Bethlehem, where he reiterated his resolve to help mediate a peace deal between the Israelis and the Palestinians and sounded upbeat about its prospects.

"The United States is here to help make that dream possible for young Jewish, Christian and Muslim children across the region," Trump said Tuesday as he stood alongside Palestinian Authority President Mahmoud Abbas.

Mistrust and alienation between black men and the police have become so entrenched that we need radical, sweeping change.

African Americans are 2.5 times more likely to be arrested than whites, and numerous studies have shown that black men are disproportionately targeted, stopped, frisked, and searched through the practice of racial profiling.

This story was updated on May 24 to clarify include new information on proposed cuts to Medicaid.

The proposed budget unveiled Tuesday by the Trump administration doubles down on major cuts to biomedical research; programs to fight infectious disease outbreaks; health care for the poor, elderly and disabled; and prevention of HIV/AIDS.

British authorities still have many questions about the Monday night concert bombing in Manchester. They don't yet know if the suicide bomber had any helpers or how he obtained his explosives.

But this much is clear: Western European cities have become regular targets over the past two years, a period coinciding with the rise of the Islamic State and its calls for supporters to strike anywhere they can and with whatever weapons are at hand.

Public support for the North Atlantic Treaty Organization has generally improved in the U.S., Europe and Canada, according to a newly released poll from the Pew Research Center.

The uptick in support comes in the wake of the turbulent U.S. presidential race where then-candidate Donald Trump called NATO "obsolete," prompting European leaders to express alarm.
