Gunmen wearing Afghan police and army uniforms have killed 40 U.S. and NATO troops so far this year, and the top American commander in Afghanistan says there is no single reason — and no simple solution.
Taliban infiltrators, disputes between NATO and Afghan security forces, and even the timing of Ramadan, the Muslim holy month, are all factors, according to Gen. John Allen.
"We think the reasons for these attacks are complex," says Allen, who spoke by video link from Kabul on Thursday. Ten of the American deaths have come in just the past two weeks.
Mitt Romney outlined an energy plan Thursday that would guide his Republican presidency. It focuses heavily on expanding the supply of fossil fuels. The presumptive nominee said the U.S., Mexico and Canada together could reach energy independence by 2020.
But the plan makes no mention of climate change and would end subsidies for cleaner sources of energy, such as wind and solar.
Twenty years ago, Homestead, Fla., was in the eye of what was then the worst storm to hit the United States.
Fifteen people died directly from Hurricane Andrew and a few dozen more died from injuries later. Tens of thousands of homes were destroyed. Andrew's 165-mile-per-hour winds took out nearly every building in Homestead, leaving tens of thousands homeless. Families spent hours in lines to get water and ice.
National Guard troops handed out bags of ice but limited how much each family could get.
