Militant Islamist fighters take part in a military parade along the streets of Syria's northern Raqqa province June 30, 2014.

The Islamic State, an al Qaeda offshoot previously known as Islamic State in Iraq and the Levant (ISIL), posted pictures online on Sunday of people waving black flags from cars and holding guns in the air, the SITE monitoring service said.

In order to get a glimpse into the visual culture of drug trade in New York City, a British photographer Graham MacIndoe collected more than one hundred bags, which were used to sell heroin. These bags feature references to various movies, fast-food restaurants, and luxury brands. This could be a way to mark various purities of heroin, or maybe different drug dealers use different markers to distinguish between each other. We can only wonder where Graham has acquired all these heroin bags. Hopefully, he picked them up after their contents were emptied. (Photo by Graham MacIndoe)

The adventurous lawyer, who lives in Ukraine, started camping in remote mountainous areas in 2007 but only came up with the concept of photographing views from his tent after a memorable trip to the Fann Mountains of Tajikistan”. – Caters News

This photographer is walking on thin ice after taking stunning photographs inside an Alaskan ice cave that could collapse at any moment. With it's dazzling turquoise walls and and huge open spaces, it's hard to imagine that this incredible frozen cavern was only formed at the beginning of 2012. But despite it's seemingly mystical allure, the fascinating natural phenomena is at risk of collapsing in on itself without warning. (Photo by Ron Gile/Caters News)
