A 12-year-old suicide bomber killed four people and wounded a dozen in eastern Afghanistan on Sunday, officials said.
The boy — thought to be one of the country’s youngest-ever suicide attackers — detonated a vest packed with explosives in a marketplace in Paktika province, on the border with Pakistan, provincial spokesman Mukhlis Afghan said in a statement.
“The head of Shkin district council, Shair Nawaz, a woman and two other men were killed and 12 others were wounded,” the statement said.
The Afghan interior ministry had earlier put the death toll at three, with 11 wounded.
Civilians are increasingly getting caught up in the violence that has blighted Afghanistan since a US-led invasion in 2001 ousted the Taliban, triggering an insurgency whose intensity has increased in recent years.
Three people rammed an explosives-laden truck into a privately-run construction site in Paktika province in March, killing 24 workers and wounding 59 others.
The United Nations says that last year was the deadliest for civilians since the conflict began, with 2,777 killed — a 15 percent increase on 2009.
Three-quarters of the deaths were caused by attacks linked to the insurgents, with improvised bombs the biggest killers, taking the lives of 1,141 people.
There has been a recent spike in suicide bombings — a key Taliban tactic — in Afghanistan along with IEDs or home made bombs which are the main cause of casualties to Afghan and international troops in the country.
About 132,000 international troops are stationed in Afghanistan, two-thirds of them from the United States, battling the Taliban and other insurgents.
A limited withdrawal of foreign troops from seven relatively peaceful areas of the country is due to start in July.
Afghan forces are set to take increasing responsibility for security as foreign troops pull back.
The worst fighting in Afghanistan usually comes in spring and summer. The Taliban insurgents have announced their spring offensive is to start Sunday.
