A bomb exploded in one of the biggest Afghan cities of Kandahar on Monday, killing four people and wounding three others, officials said.
The bomb was hidden outside the home of a former militia commander who was allied to the U.S.-backed Northern Alliance, which swept the Taliban from power in late 2001, said deputy police chief Abdul Hakim Hungar.
The blast killed the former commander, Agha Shah, a supporter of President Hamid Karzai, as well as three other civilian passers-by, he said. The three injured were rushed to hospital.
He said it was not immediately clear if the blast was because of a personal dispute or was an attack by Taliban rebels.
The bombing came a day after a suicide attack in the city injured four British government officials.
Insurgents have stepped up attacks against people allied to Karzai's U.S.-backed government, as well as international security forces here, leaving more than 1,300 dead in the past half year, reports the AP.
