The attacks late on Friday have not been confirmed by Pakistan or independent sources, but they are said to have been carried out against a border area in Afghanistan, according to a high-ranking Taliban representative.
Pakistan has broken the ceasefire and bombed three places in (the province of) Paktika, said the Taliban representative who demanded to remain anonymous.
Representatives of a hospital in Afghanistan tell the news agency AFP that ten people were killed in the attack on Friday.
Fighting and attacks between Afghanistan and Pakistan have escalated recently, with a number of people killed in skirmishes and battles along the border between the two countries.
Late on Wednesday, both Pakistan and the Taliban regime in Afghanistan confirmed that a two-day ceasefire would begin.
On Friday afternoon, the declared ceasefire formally ended without comment from either side.
The Taliban claimed that Pakistan had broken the ceasefire, and the representative of the Taliban regime told AFP that they would avenge.
