A major manhunt is under way after an improvised explosive device exploded on a London Underground train, injuring 29 people in what police have called a terrorist incident.None of the injured are thought to be in a serious or life-threatening condition, according to the London Ambulance Service, which took 19 of the injured to hospitals. Ten others went to hospitals on their own.The blast occurred during the morning rush hour at about 8:20 a.m. local time (3:20 a.m. ET) Friday at Parsons Green Tube station, a leafy stop on a busy commuter line from southwest London into the center of the capital."We now assess that this was a detonation of an improvised explosive device," London's Metropolitan Police Assistant Commissioner Mark Rowley said at a news conference.Most of the injuries appear to be the result of flash burns, he said.No arrests have been made so far. Hundreds of detectives are working on the inquiry with the support of Britain's domestic intelligence service, MI5.Mark Rowley, assistant commissioner of the London Metropolitan Police, said that investigators were making "excellent progress" in identifying, locating and arresting those responsible.A British security source who has been briefed on the investigation told CNN that a timer was found on the device. It's clear the device was intended to cause much greater damage, the source said, but cautioned that the investigation is still in its preliminary stages.Another source briefed by investigators told CNN that an initial assessment of the device indicates it is "highly likely" to have contained the explosive TATP but that this has not been confirmed. It also appeared to have been crude and poorly designed, the source said.The terror threat level in the United Kingdom was raised from severe to critical, Prime Minister Theresa May announced, a spokesperson told CNN. The terror threat level of "critical" means than another attack is considered to be "imminent.""Police and security services are obviously doing all the work to discover the full circumstances of this cowardly attack and try to identify those responsible," she said."The threat of terrorism that we face is severe but together, by working together, we will defeat them."She added that people should carry on with their daily lives but be vigilant.  2320

A federal appeals court handed the Trump administration a partial victory Monday, granting its emergency request to allow parts of its latest travel ban to go into effect while the appeal is pending.A three-judge panel -- all appointed by former President Bill Clinton -- on the 9th US Circuit Court of Appeals decided Monday to keep the lower court's order in place, freezing the ban, for foreign nationals who have a "close familial relationship" with a person in the United States, but granted the Trump administration's request to allow it to go into effect for everyone else.The 9th Circuit panel is set to hear oral arguments on the case on December 6.President Donald Trump signed an executive order in January banning foreign nationals from specific Muslim-majority countries from traveling to the United States, but the restrictions have been tied up in the legal system and have since been revised multiple times.In October, a federal judge in Hawaii blocked the third iteration of the travel ban one day before it was scheduled to take effect.At the time, Judge Derrick Watson said it "plainly discriminates based on nationality."The ban targeted foreign nationals from eight countries -- Chad, Iran, Libya, North Korea, Syria, Venezuela, Somalia and Yemen -- with varying levels of restrictions.The second version of the travel ban, issued in March, had barred residents of six Muslim-majority countries -- Iran, Syria, Libya, Sudan, Somalia and Yemen. 1487

A growing number of Hispanics along the Texas-Mexico border with birth records showing they were born in the United States are being denied American passports, held in immigration detention centers, and entered into deportation proceedings, immigration attorneys and individuals affected told the Washington Post.According to the Post report, the issue stems from a government allegation that from the 1950s through the 1990s, midwives and physicians working along the border issued American birth certificates to babies born in Mexico, which some birth attendants have admitted to in court.The State Department, the Post said, denies changing its "policy or practice regarding the adjudication of passport applications." The agency also said the border region "happens to be an area of the country where there has been a significant incidence of citizenship fraud." 874

A major crackdown could be coming to stop those annoying robocalls. New research from YouMail--a company that developed robocall blocking software--shows each person on the country receives about 150 robocalls a year.Alex Quilici, CEO of YouMail, says these terribly annoying calls keep increasing for two reasons. "One is there are more and more scam calls. The second thing that's driving the increase is people aren't answering the phone anymore," Quilici says.Because people don’t answer their phones, it makes the robocallers place more calls, he says.It’s a problem both Democrats and Republicans can agree on.  Senators John Thune, R-South Dakota, and Ed Markey, D-Massachusetts, have proposed bipartisan legislation to increase the penalties for robocalls to ,000. They are also proposing to extend the time after a crime in which prosecutors must bring their case from one years to three years.Commercial robocalls are illegal, but the Federal Trade Commission, which is tasked with investigating and charging those who have violated the anti-Robocall federal law, has a hard time prosecuting offenders within the current one-year time limit. “If you look at the current enforcement efforts, there's been a 0 million fine and million fine that's covered people who've made 100 million robocalls or a couple hundred million robocalls. That's a drop in the bucket of the nearly 50 billion we're going to have this year,” Quilici. “It's going to take a lot more than just enforcement and some better regulation to solve the problem."Until legislation to crack down on people who make robocalls passes, Quilici suggests:  1674
