Kabul - A suicide attack injured at least three civilians early Tuesday morning in the Bagh-e-Babar area of the Afghan capital Kabul, an Afghan official said.

"Based on the initial reports, a suicide bomber was trying to target the Afghan National Army staff bus but could not get to his target and the blast injured only civilians," said General Ali Shah Paktiawal, crime branch head at Kabul's police department.

The bomber blew himself up near the famous and historic area of the city, he said.

The bomber was also killed in the incident, according to the police statement.

This is the second suicide attack in two weeks in the Afghan capital.

A suicide attack on the Indian embassy on July 7 killed more than 50 and injured 140 others. (dpa)
