Today's edition of quick hits:
* Air Algerie Flight AH5017: "A commercial jetliner carrying 116 people disappeared over west Africa after losing contact with air traffic controllers early Thursday, a Spanish charter company said. Air Algerie Flight AH5017 vanished about 50 minutes after it left Ouagadougou, Burkina Faso, according to the Algerian Press Service. The jet took off at 1:17 a.m. local time (9:17 p.m. ET on Wednesday) bound for Algiers, Algeria."
* Gaza: "A series of explosions at a school run by the United Nations sheltering hundreds of Palestinians who had fled their homes for safety from Israeli military assaults killed at least 16 people on Thursday afternoon and wounded many more. The cause was not immediately clear."
* Ukraine: "Arseniy Yatsenyuk resigned as Ukraine's prime minister Thursday after the ruling coalition in parliament collapsed, accusing lawmakers of imperiling the nation by putting politics above urgent needs during wartime."
* Iran: "Three American citizens, including The Washington Post's correspondent in Iran, appear to have been detained this week in Tehran, U.S. officials and the newspaper said Thursday."
* Gun violence in Pennsylvania: "A gunman opened fire inside a hospital psychiatric unit on Thursday, leaving one hospital employee dead and a second injured before being critically wounded himself, a prosecutor said."
* Border crisis: "As House Republicans struggle to figure out whether their proposed response to the border crisis can pass the House, given opposition to action among conservatives, it's increasingly likely they'll need House Dems to get anything through the lower chamber." Democrats are leaving Republicans with two choices, neither of which the GOP will like.
* This seemed unimaginable six weeks ago: "Negotiations between the House and Senate over legislation reforming the Veterans Affairs Department melted down on Thursday, raising the probability that Congress will leave for the August recess without approving a bill."
* He's right: "Sen. Tom Harkin (D-IA), the chairman of the health committee and a chief author of Obamacare, tore into an appeals court ruling this week that forbid the federal exchange to provide subsidies to millions of Americans in 36 states. 'It's nuts,' he told TPM in an interview in the Capitol on Thursday."
* The jokes write themselves: "New Jersey Gov. Chris Christie took the 'upper level' -- helicoptering over the George Washington Bridge -- to beat rush hour traffic from his home state to a recent GOP fundraiser with Connecticut gubernatorial contender Tom Foley."
* Keep an eye on this one: "Sen. Jay Rockefeller (D-W. Va.) has accused House oversight committee chairman Darrell Issa (R-Calif.) of inappropriately intervening in an ongoing Federal Trade Commission case against a company being represented by a legal group run by a former Issa staffer."
* Craziest quote of the day: "Rep. Trent Franks (R-Ariz.) on Thursday equated Russian President Vladimir Putin's involvement in the downing of Malaysia Airlines Flight 17 to President Obama's responsibility for the immigration crisis at the southern U.S. border."
