A suicide bomber said to be aged 12 has killed four people in east Afghanistan, one of several attacks a day after the Taliban announced a spring offensive.
A dozen people were injured as the suicide bomber struck a crowded market in Paktika province, killing a local official, a woman and two other men.
In Ghazni City, a gunman opened fire at a police checkpoint, killing two police officers and two civilians.
A bicycle bomb near the city's police station wounded 13 civilians.
The BBC's Paul Wood in Kabul says some believe the suicide bomber, if he was 12, would be one of the youngest ever to have staged such an attack.
He says by one count there are more than 150 would-be suicide bombers between 13-17 years of age who have been intercepted by the Afghan security forces.
On Saturday the Taliban declared a new campaign to attack foreign troops, Afghan security forces and government officials.
International organisations, including the UN, have warned their staff not to go out unless it is absolutely necessary.
In Kandahar, in the south, and in other cities across the country, thousands of extra soldiers and police have been deployed.
A gradual withdrawal of foreign combat troops is set to begin in July as part of a handover to Afghan security forces.
