Police said a suicide bomber detonated his explosives outside a press club in northwestern Pakistan on Tuesday, killing at least two people in the latest of a slew of attacks to strike the city of Peshawar since the military launched a major offensive near the Afghan border.
A woman who was at the site of the attack apparently died of cardiac arrest, according to a doctor at a hospital where the three bodies were brought.
A policeman tried to search the attacker as he approached the press club's gate, but the man resisted and was able to trigger his explosives, killing the officer and an accountant who worked for the organisation, said Peshawar's police chief.
Adil Khan, a local photographer who was inside the press club when the attack occurred, said he heard the police officer at the gate, Muhammad Riaz, trying to force the bomber to submit to a search.
"Suddenly a big explosion occurred and smoke made me unable to see immediately what happened," said Khan. "After a while, I saw Riaz and accountant Mian Iqbal lying dead in a pool of blood and there were some scattered body parts."
Seventeen other people were injured in the attack, many of whom were travelling in a bus that passed the press club when the explosion occurred, said doctors.
The blast blew out the press club's windows and slightly damaged the gate and several surrounding buildings.
Peshawar has been hit by at least seven attacks in the past two months in retaliation for a military offensive launched in mid-October against the militant stronghold of South Waziristan in Pakistan's lawless tribal area near the Afghan border.
A single attack in late October in a market popular with women and children in Peshawar killed 112 people.
The Peshawar Press Club targeted in Tuesday's attack is a well-known landmark in the city, and many journalists congregate there.
A provincial labour minister was scheduled to hold a press conference at the press club later Tuesday, according to the organisation's president.
He praised Riaz, the police officer who prevented the bomber from entering the building.
