Twelve people have been arrested in London after three attackers killed seven people and injured 48 more on Saturday night. The three attackers were shot dead by police. It’s the third terror attack in the U.K. in three months. British Prime Minister Theresa May has vowed a sweeping review of the nation’s counterterrorism strategy. All of this comes as the country gears up for national parliamentary elections scheduled for this Thursday. Prime Minister May has also called for increased web surveillance so the internet is no longer a "safe space" for terrorists. Meanwhile, President Donald Trump used the London attacks to call for the United States to impose his proposed Muslim travel ban. Here to discuss all of this with Democracy Now! is Guardian columnist Paul Mason.
