You're watching multisource global video news analysis from Newsy.

This is Newsy Now, and here are your latest headlines. 16,000 police officers descend on London’s streets trying to stop a fourth day of rioting. Some shops and businesses in the area are closing early hoping to avoid a fourth night of violence. The BBC captures the images--of a town on fire.

“Well right now, my house is on fire. My neighbor’s house is on fire. It’s bedlam on the streets. People have been rioting, openly rioting this place for about an hour or two, since I got here. The police are absolutely ineffectual. They’ve done nothing.”

Staying in London--police are combing through Blackberry messages to locate rioters. Blackberry maker -- Research In Motion -- is allowing police to look through messages.  Now hackers are targeting RIM in response. CNBC explains -- why police are targeting the cell phone giant.

“The point is the rule of law and order relies on people having a certain degree of trust and reliance. If you think you can gather 300 people together using your BlackBerry messenger, there’s too many to be stopped. This is opportunistic violence.”

In world news -- the UN will meet to discuss how it can help farmers suffering from drought in the Horn of Africa. The UN just landed its first plane into Mogadishu in five years. But Al Jazeera says -- more help is still needed.

“Carrying all that they have left in this world, thousands of Somalis are now streaming into this city looking for food. There’s more food in this city, but it’s still not enough.”

In U.S. news -- Florida police release car chase video involving three siblings suspected of robbery. The three are also accused of shooting at police during a high speed chase. The chase at times hit 100 miles per hour. Take a look.

“Officer: Nat Sound. Holy ****.”
Reporter: “Those shots you just heard are of at least 20 police say the Dougherty siblings fired at a  Zephryhills officer. It was just hours after that when Ryan, Dylan, and Lee-Grace  Dougherty again fired their high powered guns as they robbed a bank in Valdosta, Georgia.”

In national news -- the swimmer trying to make it from Cuba to Florida---calls it quits. Diana Nyad had completed about half of her 60 hour trip. The swim takes about 103 miles to complete. Here’s HLN.

“She was overwhelmed with exhaustion and emotion after calling it quits. Nyad was trying to become the first person to swim from Cuba to Florida without a shark cage. She stopped halfway through the 103 mile journey because of shoulder pain and asthma, and she is deeply disappointed, but she says she made the right call.”
