Islamabad, Pakistan (CNN) -- At least six people were killed and 15 wounded in a suicide attack targeting a political rally in northwest Pakistan on Monday, officials said.

The blast took place in Butgram, about 130 kilometers (80 miles) north of Islamabad in Khyber Pakhtunkwa province. The province was formerly known as the North West Frontier Province.

Amir Muqam, a senior leader of the Pakistan Muslim League (PML-Q), was scheduled to address the rally, said senior government official Khalid Umarzai.

The lawmaker had not yet arrived when security personnel stopped the alleged bomber at the entrance to the event, Umarzai said.

The bomber then detonated explosives, he said.

Among those killed were two police officers, two women and a child, Umarzai said.
