Today's edition of quick hits:* Manchester: "The suicide bomber who killed 22 people after an Ariana Grande concert was part of a network that included his brother, who was arrested Wednesday as he was allegedly plotting a terrorist attack on the Libyan capital of Tripoli."* Low expectations: "President Trump arrived in Belgium on Wednesday for an audience with the nation's king, a day ahead of meetings with leaders of alliances he once derided as irrelevant — and many top officials here say they will count it a success if there are no blowups during the visit."* Nice one, Pope Francis: "During an initially awkward meeting in Vatican City, Francis presented President Trump with a signed copy of 'Laudato Si' -- the pontiff's 192-page work calling for a new partnership between science and religion to combat human-driven climate change.

Consider this an open thread.
