Dutch Safety Board: Buk missile downed MH17 in Ukraine
GILZE-RIJEN AIR BASE, Netherlands (AP) - A missile launched from rebel-held Ukraine ripped the cockpit from Malaysia Airlines Flight 17, Dutch investigators reported Tuesday, adding that some passengers may have remained conscious for another minute or so as the airflow tore off their clothes and objects spinning through the cabin killed people in neighboring seats. The investigators said in their final report that the Buk missile that downed the Boeing 777 exploded less than a meter from the cockpit, killing the two pilots and the purser inside in an instant and breaking off the front of the plane. While some of the passengers may have been conscious in the up to 90 seconds it took to hit the ground, they probably were not fully aware of what was happening amid the oxygen-starved, freezing chaos.

Israeli leader vows 'aggressive steps' to halt fighting
JERUSALEM (AP) - Israel's prime minister on Tuesday said he would take a series of "aggressive steps" to halt a wave of violence in Israeli cities after two attacks in Jerusalem left three Israelis dead. Three Palestinians, including two attackers, were also killed. The attacks in Jerusalem, including a deadly shooting and knifing spree on a bus and a violent hacking attack caught on video, escalated the monthlong unrest and raised the pressure on Prime Minister Benjamin Netanyahu to take action. The government has been unable to stop the violence, carried out mostly by young Palestinians unaffiliated with known militant groups and apparently acting on their own.

Clinton, Sanders rivalry in spotlight as Democrats debate
WASHINGTON (AP) - Hillary Rodham Clinton says she always expected tough competition in the Democratic presidential primary. It's likely she didn't expect it would come from Bernie Sanders, the rumpled independent senator from Vermont and a self-described democratic socialist calling for "political revolution." The surprise rivalry between Clinton and Sanders will be at the forefront as Democrats take the stage Tuesday in Las Vegas for the party's first debate of the 2016 campaign. The senator and the former secretary of state will be joined by a trio of candidates who occupy the basement of early polls, each looking to change their fortunes with a breakout moment in prime time.

AP Exclusive: Clinton email server setup risked intrusions
WASHINGTON (AP) - The private email server running in Hillary Rodham Clinton's home basement when she was secretary of state was connected to the Internet in ways that made it more vulnerable to hackers while using software that could have been exploited, according to data and documents reviewed by The Associated Press. Clinton's server, which handled her personal and State Department correspondence, appeared to allow users to connect openly over the Internet to control it remotely, according to detailed records compiled in 2012. Experts said the Microsoft remote desktop service wasn't intended for such use without additional protective measures, and was the subject of U.S. government and industry warnings at the time over attacks from even low-skilled intruders.

Planned Parenthood to forgo payment in fetal tissue programs
NEW YORK (AP) - Responding to a furor over undercover videos, Planned Parenthood says it will maintain programs at some of its clinics that make fetal tissue available for research, but will no longer accept any sort of payment to cover the costs of those programs. Anti-abortion activists who recently released a series of covertly filmed videos have contended that Planned Parenthood officials sought profits from their programs providing post-abortion fetal tissue to researchers. Planned Parenthood said the videos were deceptively edited and denied seeking any payments beyond legally permitted reimbursement of costs. The new policy - forgoing even permissible reimbursement - was outlined in a letter sent Tuesday by Planned Parenthood's president, Cecile Richards, to Francis Collins, the director of the National Institutes of Health.

Donald Trump to host 'Saturday Night Live'
NEW YORK (AP) - Republican presidential candidate Donald Trump has agreed to host "Saturday Night Live" next month. NBC said its former "Celebrity Apprentice" host will be the headliner of the Nov. 7 show. It's the second time he has hosted the venerable comedy institution; he was on the show in April 2004. Trump was also skewered in the season premiere's opening sketch. Trump has been ratings gold for nearly every television outlet he's touched since his candidacy took off this summer, the main reason behind record viewership for the two GOP candidates' debates in August and September. Sia will be the "Saturday Night Live" musical guest on the night that Trump hosts.

Court reinstates lawsuit over NYPD surveillance of Muslims
PHILADELPHIA (AP) - A federal appeals court on Tuesday reinstated a lawsuit challenging the New York Police Department's surveillance of Muslim groups in New Jersey after the Sept. 11 terrorist attacks, saying any resulting harm came from the city's tactics, not the media's reporting of them. The 3rd U.S. Circuit Court of Appeals, reversing a judge's decision last year to dismiss the case, found the Muslim plaintiffs raised sufficient allegations of religious-freedom and equal-protection violations. The court compared the spying to other instances of heightened scrutiny of religious and ethnic groups, including Japanese-Americans during World War II. In dismissing the lawsuit, U.S.

Starbucks starting delivery on Empire State Building
NEW YORK (AP) - Starbucks will start offering delivery within the Empire State Building Tuesday, giving office workers in the skyscraper the option of paying a $2 fee to avoid making a trip to the lobby. The Seattle-based coffee chain says 12,000 employees who work in the New York City building will be able to place orders on a designated website, and have their food and drinks delivered within a half hour. The orders will be delivered to a drop-off area, such as the office's reception desk. Starbucks Corp. says the service is in line with its push to make its offerings increasingly convenient.

Twitter purging up to 336 workers as new CEO slashes costs
SAN FRANCISCO (AP) - Twitter is laying off up to 336 employees, signaling CEO Jack Dorsey's resolve to slash costs while the company struggles to make money. The cutbacks announced Tuesday could equate to about 8 percent of Twitter's workforce of 4,100 people. The purge comes two weeks after Twitter brought back one of its co-founders as permanent CEO in hopes that Dorsey would be able to resolve problems that have slowed user growth at the messaging service and compounded an uninterrupted cycle of financial losses. Cutting costs can boost profits but at Twitter, it has also raises uncertainty about the future, the company's pursuit of faster growth and its ability to attract a bigger audience.

Playboy to stop running pictures of completely naked women
LOS ANGELES (AP) - Playboy is about to find out how many people really do read it for the articles. The magazine that helped usher in the sexual revolution in the 1950s and '60s by bringing nudity into America's living rooms - or at least its sock drawers - announced this week that it will no longer run photos of completely naked women. Playboy has seen its circulation plunge in recent decades as it has fallen victim to some of the very forces it helped set in motion. First it had to deal with competition from more sexually explicit magazines like Penthouse and Hustler.
