Story highlights The Taliban denies responsibility for explosions at funeral of senator's son

The blasts come in the run-up to next week's regional peace summit in Kabul

Kabul, Afghanistan (CNN) Seven people died Saturday in Kabul when suicide bombers struck the funeral of a man killed during anti-government protests, Afghan official said.

"Three big bangs" went off at the funeral of Salem Izadyar, the son of Mohammad Alam Izadyar, first deputy chairman of the Afghan Senate, a witness told CNN.

The Taliban denied involvement in the funeral attack, which injured 119 people.

The blasts were from three suicide bombings, said the government's chief executive, Abdullah Abdullah, who attended the funeral and tweeted he was not harmed. Abdullah described the attack on TV, Sune Engel Rasmussen of The Guardian said on CNN.

Injured men gather in the back of a pickup truck after the Saturday blasts.

Lawmakers and high-profile government officials attended the funeral, including those from the senator's Jamiat-e Islami party, Rasmussen said. Jamiat is a largely Tajik political movement and an adversary of the Taliban.
