Three people have been killed and up to 10 wounded in a suicide bomb attack in Kabul.
The Interior Ministry said the bomber targeted an Afghan army bus.
The Taliban claimed responsibility for the attack that mirrored a double bombing just a day earlier.
On October 1, Taliban suicide bombers struck two buses carrying Afghan soldiers in Kabul, killing seven people and wounding 21.
That attack came a day after Afghanistan signed security deals with NATO and the United States.
The agreements will allow foreign troops to stay in the country after the end of the year, filling a campaign promise by new President Ashraf Ghani.
In claiming responsibility for the October 1 bombings, the Taliban criticized Ghani and his government for allowing foreign troops to stay after the year ends, calling it a "stooge regime."
