Pakistani authorities say a suicide bomber has killed at least 24 people and wounded 25 others, including the country's interior minister.
Police say the attack in northwestern Pakistan occurred while people were gathering around Aftab Ahmed Khan Sherpao following a public meeting in the town of Charsadda on Saturday.
A spokesman for the interior minister says the attack was definitely a suicide bombing. Security guards blocked the attacker as he tried to get close to Sherpao.
Officials say the interior minister, who is involved in Pakistan's efforts to fight regional terrorism, was wounded but in stable condition.
Officials say they have found the head and torso of the bomber, but are still trying to learn his identity.
The attack is the latest in a series of bombings targeting Pakistani officials since the country became a US ally in the fight against terrorism in 2001.
It came as Pakistani President Prevez Musharraf is preparing to meet in Turkey to discuss border security with his Afghan counterpart, Hamid Karzai.
