Tight Security in Kabul for US Envoy Visit

Afghan troops are filling the streets of Kabul in preparation for the arrival of the new U.S. envoy to the region, a day after the Taliban carried out deadly attacks in the Afghan capital. Richard Holbrooke is expected to visit Afghanistan Thursday for his first trip to the country. Officials say they had already planned increased security for the envoy, but Holbrookes arrival comes after Wednesdays near-simultaneous attacks on three government buildings in Kabul. At least 26 people were killed and nearly 60 others wounded in the Taliban assault.
