the charge in the driver's seat will be afghan security forces. officials say they've made a lot of improvements over the past few years, but critics say they're poorly trained and there's no way that they're going to be able to defend this country on their own. so lots of huge tests for them and a lot riding for what nato accomplished here, what u.s. accomplished over here over the past 12 years. another big development today, president karzai announcing that he has approved the taliban opening an office in qatar. that's where the afghanistan government is planning to hold peace talks with the taliban moving forward. a lot of unknowns in that process as well. >> challenges ahead to be sure. thank you so much. today, protests in brazil. many brazilians upset about a fare increase. the price of a bus ticket from $1.38 to $1.47, which is a large fee based on the average income in that nation.
