British Prime Minister Theresa May has called the Manchester terror bombing, which targeted the venue of an Ariana Grande concert last night, the "worst attack the city has experienced, and the worst ever to hit the north of England."

May said police believe they know the suicide bomber who detonated the explosive inside the concert venue, and they arrested a 23-year-old man, identified as Salman Abedi, early this morning. The Islamic State has also claimed that one of their members carried out the attack, which killed at least 22 people.

Russian President Vladimir Putin said Russia is ready to increase anti-terrorism cooperation with Britain following the latest attack. And France's interior minister said early Tuesday morning that the government will work with event organizers on how to better secure public spaces moving forward — especially after the November 15 attacks at a concert venue, cafes and bars.

Why it matters: The concert venue attack is an attack on one of Britain's cultural hubs, as Manchester has long served as a primary cultural influence on Britain with bands like The Smiths and Oasis, as well as soccer rivalry between Manchester United and Manchester City teams.

More statements from officials:

  • "This attack stands out for its appalling, sickening cowardice," said May.
  • "This is horrific, this is criminal. May the perpetrators face the full weight of justice both in this life and the next," said Harun Khan, the secretary general of the Muslim Council of Britain.
  • Britain's Finance Minister Philip Hammond was scheduled to speak at a panel in Brussels, but is returning to London.
  • Paris mayor's office said that all concerts and shows they have scheduled will continue as planned. Grande is set to perform there on June 7.

How small businesses got stiffed by the coronavirus pandemic

The story of American businesses in the coronavirus pandemic is a tale of two markets — one made up of tech firms and online retailers as winners awash in capital, and another of brick-and-mortar mom-and-pop shops that is collapsing.

Why it matters: The coronavirus pandemic has created an environment where losing industries like traditional retail and hospitality as well as a sizable portion of firms owned by women, immigrants and people of color are wiped out and may be gone for good.

Millions of angry gamers may soon join the chorus of voices calling for an antitrust crackdown on Apple, as the iPhone giant faces a new lawsuit and PR blitz from Epic Games, maker of mega-hit Fortnite.

Why it matters: Apple is one of several Big Tech firms accused of violating the spirit, if not the letter, of antitrust law. A high-profile lawsuit could become a roadmap for either building a case against tech titans under existing antitrust laws or writing new ones better suited to the digital economy.

Survey: Fears grow about Social Security’s future

Younger Americans are increasingly concerned that Social Security won't be enough to wholly fall back on once they retire, according to a survey conducted by AARP — in honor of today's 85th anniversary of the program — given first to Axios.

Why it matters: Young people's concerns about financial insecurity once they're on a restricted income are rising — and that generation is worried the program, which currently pays out to 65 million beneficiaries, won't be enough to sustain them.
