It's been a day of deadly violence in Afghanistan. A wave of Taliban attacks has left nearly 20 people dead, including two U.S. soldiers who were killed during a suicide bombing of a U.S. military convoy.

These attacks come ahead of the formal end of the U.S. and NATO mission in Afghanistan at the end of the month.

John Huddy reported on "America's News Headquarters" today that the Taliban is warning that these attacks will continue as the international military effort in Afghanistan winds down.

"It's been a bloody day and, for that matter, a bloody 24 hours," Huddy said.

He reported that those two U.S. soldiers were killed yesterday, and there were also two separate attacks in Kabul today. A suicide bomber blew up a bus carrying Afghan soldiers, killing six and wounding 14 others, and two gunmen shot to death an Afghan Supreme Court official who was walking to his car.

Huddy said that insurgents also shot to death 12 workers who were clearing mines in southern Afghanistan.

"The Taliban is warning that attacks will continue specifically on government officials, military forces and foreigners, and that includes the media as well," Huddy concluded.
