In Afghanistan today, the Taliban has launched a string of attacks across the country, including coordinated strikes in the capital, Kabul, that hit near western targets and Afghan government buildings. The Taliban says today's attack marks the beginning of what they call the spring fighting season, the period after the winter thaw when mountain passes and roads become accessible again.
There are fresh fears about the infiltration of Afghan security forces by anti-government and anti-American insurgents after the discovery of 10 or 11 (depending on the media report) suicide vests inside the headquarters of that country's defense ministry and the arrest of more than a dozen soldiers.
The killings of some 16 civilians in Afghanistan on Sunday allegedly by a U.S. soldier are raising new questions about U.S. military strategy: whether the surge of American troops worked, and whether the U.S. troops have won over the Afghan people or alienated them.
The place where the killings happened was a "no-go zone" for American and even Afghan troops as recently as two years ago — it was Taliban country.
In Afghanistan, the killings are called "green on blue" — that's when an Afghan soldier or police officer turns his gun on a NATO ally.
There was a wave of such violence just last month after U.S. soldiers accidentally burned Korans. Over the next week, six Americans were killed, apparently at the hands of Afghans working with the U.S.
The top U.S. and NATO commanders in Afghanistan think they have some answers to this recurring problem, and it's up to U.S. soldiers like Capt. Joe Fritze to see if they work.
