The Taliban have claimed responsibility for the attack, saying that Laghmani was the target. The insurgents said that the province's Governor and Police Chief were unhurt.
A communique from President Hamid Karzai said that 24 people were killed in all and contradicted an earlier claim by The National Intelligence Directorate that Laghmani was wounded but had survived the attack.
Provincial government spokesperson Sayed Ahmad Safi said the attack took place after a meeting on drugs and security.
"As the participants were leaving the mosque after the meeting there was a suicide explosion outside," he said.
Other local officials say that 54 people were injured.
The killing is "a big blow to the government", says reporter Behroz Khan in the Pakistani city of Peshawar.
"The intelligence department is providing information to the government and other rebels and now the intelligence department itself is the target of suicide bombing."
Khan says that officials will now suspect that Taliban sympathisers within their ranks are giving information to the rebels.
