An early-morning airstrike on Kabul's outskirts killed at least 10 people today - the second apparent stray strike in less than 24 hours to cause fatalities.
At the scene of the strike on the northern edge of Kabul, an AP reporter saw the bodies of four children and two adults, and neighbours said there were more dead.
Word of the latest strike gone awry comes a day after an apparent errant bombardment hit a village behind the rebel military alliance's battle lines north of Kabul. At least one woman was killed and 10 hurt in that strike, according to witnesses.
The US warplanes striking north of Kabul appeared to be targeting military installations backing up Taliban front lines. Taliban anti-aircraft fire rang out as the planes flew overhead, but the salvos were ineffective against the high-flying jets.
Overnight, the roar of jets - and answering anti-aircraft fire - could be heard occasionally, but there was no bombardment in the city centre itself.
Today's daylight raids followed what witnesses called the heaviest such strikes of the three-week-old air campaign on Taliban front lines in the north of Afghanistan - including the apparent accidental hit on the village of Ghanikheil, on the Shomali plain north of Kabul.
Villagers said two mud houses were hit. In one of them, the family was preparing for a wedding, they said.
In the worst-hit house, villagers said a 20-year-old woman was killed and six others hurt. Four others were hurt in the second house, they said.
"The sound was huge. The plane swooped down - I could hear it dive," said another eyewitness, Mr Amin Ullah, 70. "I heard the huge explosion."
In Washington, Pentagon spokesmen said last night they could not confirm accounts that the village was hit.
Rebels confronting Taliban troops north of the capital, Kabul, have been complaining publicly that the American airstrikes were not doing enough to advance their cause. It wasn't known if yesterday's raids were in response to that, but an opposition spokesman said he was pleased with the day's raids.
North of Kabul, US jets dropped massive bombs yesterday in an offensive that lasted most of the day. Witnesses called it the fiercest such assault on the Kabul front since the start of the air campaign on October 7th.
