A logging truck is pictured among burned trees, felled following last year's Rim fire, near Groveland, California July 30, 2014. Long, heavy logging trucks, swaying with the weight of charred California pines, wind through the forest near Yosemite National Park, part of an effort to clean up from last year�s devastating wildfires even as new blazes break out this summer.

Yazidi fighters who recently joined the Kurdish People's Protection Units secure a road in Mount Sinjar
Yazidi fighters who recently joined the Kurdish People's Protection Units (YPG) secure a road in Mount Sinjar in northern Iraq, which is used by displaced people from the Yazidi religious minority fleeing violence from forces loyal to the Islamic State in Sinjar town and making their way towards Newrooz camp in Syria's al-Hasakah province August 13, 2014. A U.S. mission to evacuate Yazidis trapped on the mountain by Sunni militant fighters is far less likely after a U.S. assessment team sent there on Wednesday found the humanitarian situation not as grave as expected, the Pentagon said.

A protester throws back a smoke bomb while clashing with police in Ferguson, Missouri August 13, 2014. Police in Ferguson fired several rounds of tear gas to disperse protesters late on Wednesday, on the fourth night of demonstrations over the fatal shooting last weekend of an unarmed black teenager Michael Brown, 18, by a police officer on Saturday after what police said was a struggle with a gun in a police car. A witness in the case told local media that Brown had raised his arms to police to show that he was unarmed before being killed. Picture taken August 13, 2014.
