As riots sweep several British cities, the U.S. State Department is cautioning Americans in the U.K. to avoid areas of civil unrest, monitor local media reports and not engage in any debates that might turn violent.
The guidance, carried on the website of the U.S. Embassy in London, is part of a well-oiled warning system the State Department has used for decades to alert Americans living or traveling in countries around the world of everything from terrorist threats to hurricanes.
Monday, the State Department issued an updated travel warning on Pakistan, cautioning U.S. citizens that Americans in the country have been "arrested, deported, harassed, and detained" for visa violations and noting that the number of U.S. citizens arrested, detained and prosecuted for overstaying their Pakistani visas "increased markedly across the country."
How does the State Department decide when to issue a travel warning as opposed to simple guidance?

A week ago, 10-year-old Braydon Nichols started to think about his dad and how much he missed him.
Army Chief Warrant Officer Bryan Nichols, a helicopter pilot, had been deployed for two months in Afghanistan.
The little boy, in the car with his mother running errands, brushed back his dirty-blond hair and ran his hand over his cheek.
Jessica Nichols looked over when she heard sniffles. Her son was crying.
"When is Dad coming back so we go camping?" he asked her.
Soon, she assured him. "Your dad is off fighting for this country."
The boy replied, "As soon as he gets home, we're going to go on a camping trip, just me and him."
Jessica Nichols cannot stop replaying that scene in her mind. That's because only a few days later, on Saturday night, she was cradling her boy who was crying once again. Except this time she could not tell him that his father was coming home. She had just received a call informing her that Bryan Nichols was one of the 30 Americans who died that afternoon when their Chinook helicopter was shot down in Wardak province in east-central Afghanistan.

Dadaab, Kenya (CNN) - Right now, this may be the most desperate place on Earth.
A drought, not seen in 60 years, compounded with near complete lawlessness and utter disregard for human life has made it so.
It is hard to imagine, but dust and starvation are nearly everywhere you look, and the world's largest refugee camp is thick with misery on this night. The smell is a combination of the acrid sweetness associated with malnourishment, anxious sweat and diesel fuel.
The fuel is used to keep away the swarming flies. It stinks more than it repels.
