(CNN) -- A 12-year-old suicide bomber killed three other people, including a district council head, and armed attackers shot to death two police officers Sunday, the first day of a Taliban spring offensive.
The attacks followed a Taliban declaration Saturday that its spring military operations will focus on attacks against military bases, airbases, convoys, heads of foreign and local companies, and members of the local government.
In Shaken district of Paktika province, the 12-year-old boy detonated explosives in his vest to kill district council head Shernawaz Khan and two others, said Mukhlis Afghan, a spokesman for the Paktika provincial governor.
The blast also wounded 12 people, Afghan said, adding: "The suicide attacker's aim was to target the district council chief."
In a separate attack, armed men opened fire on police in southern Ghazni province, killing two police officers, provincial police security commander Abdul Hassan said.
