Both times, the U.S military blamed militants for putting innocent lives in danger.
But Karzai has repeatedly pleaded for western troops to show more restraint amid concern that civilian deaths shake domestic support for the foreign military involvement that the president needs to prop up his weak government - increasingly under threat from a resurgent Taliban.
In the latest incident, militants late Sunday fired on a U.S. base in Kapisa province, just north of Kabul, prompting the air strike on Jabar village.
The strike hit a civilian home, killing four women, four children between the ages of six months and five years, and one elderly man, said Gulam Nabi, a relative of the victims.Sayad Mohammad Dawood Hashimmi, Kapisa deputy governor, confirmed the nine deaths, as did an Interior Ministry official in Kabul, who asked not to be identified because the ministry had not yet prepared a statement.
A U.S. military statement said two men with automatic rifles were seen heading into a compound of five homes after a rocket attack on a U.S. base in the area.
"These men knowingly endangered civilians by retreating into a populated area while conducting attacks against coalition forces," said Lt.-Col. David Accetta, a U.S. military spokesman. "We observed the men entering a compound and that compound was targeted and hit by an air strike."
The statement said coalition forces "dropped two 2,000-pound bombs" on the compound after a rocket was fired at the base and armed militants were seen moving into the compound. The U.S. base in Kapisa is about 80 kilometres northeast of Kabul, the capital.
Among those killed were Gulam Nabi's parents, his sister, his nephew, and four of the extended family's youngest children.
The news of the air strike came a day after wounded Afghans and witnesses said U.S. marines fired on civilians after a suicide bombing in eastern Nangahar province. The violence that left up to 10 Afghans dead and 34 wounded, sparked angry anti-U.S. demonstrations by hundreds of Afghan men.
A U.S. official called The Associated Press on Monday to say that military authorities believe Sunday's suicide bombing was a "clearly planned, orchestrated attack" that included enemy fire on the convoy and a planned demonstration.
The official, who asked not to be identified because of the sensitivity of the matter, said authorities believe criminal elements orchestrated the attack and demonstration and that it was related to ongoing Afghan efforts to eradicate the region's profitable opium poppy crop.
