The Taliban said at least five civilians were killed and six wounded in US bombings overnight.
The Taliban also said it has executed a former Afghan resistance commander Abdul Haq.
The claim came as Britain announced 200 commandos were immediately available to join the US-led coalition against the Taliban while 400 commandos will be put on high readiness.
US-led jets dropped up to 10 bombs on the Taliban front line north of the Afghan capital overnight in the strongest attack on the city in days.
Taliban officials said at least five civilians were killed in the raids.
While witnesses reported two young girls were among those killed when a US bomb landed on a village on the outskirts of Kabul this morning and destroyed three houses.
The jets repeatedly struck targets near Kabul's airport, the city centre, and to the north and west. The assault lasted past midnight and involved at least 10 waves of warplanes.
Gunners for the ruling Taliban responded with heavy anti-aircraft fire.
Bombing to the north of the capital was to secure control of the strategic Bagram airport. It is held by the Northern Alliance but cannot be used because of Taliban fighters in the hills around it.
US jets were also in the skies near Taliban-held Mazar-e-Sharif, striking Taliban positions to the south and east of the strategic city. Its capture by the Northern Alliance would open up crucial supply routes to Tajikistan and Uzbekistan.
Opposition officials in Uzbekistan say a Taliban commander, Mr Mullah Yusuf, and 10 other Taliban fighters were killed in the bombing near Mazar-e-Sharif.
The opposition also claimed its troops captured the village of Shurchi on the southern outskirts of Mazar-e-Sharif and took 180 Taliban prisoners.
