At least 11 people were wounded when militants staged attacks on government buildings in the restive southern Afghan city of Kandahar on Saturday, a local official told CNN.
The Taliban claimed responsibility for the strikes, and it said the assault is part of its Bader operation, the codename for the group's spring offensive launched last week.
The targets were the National Directorate of Security, a police headquarters, the Kandahar city headquarters, and the provincial governor's office, according to the Taliban and a provincial governor's spokesman.
The police officers were among the wounded, said Zelmai Ayoubi, a spokesman for the Kandahar governor.
"From the beginning of this attack, more then 10 explosions have been happened across Kandahar city," Ayoubi said about Saturday's events.
Afghan officials said gunfights between security forces and militants persisted later Saturday in various locations across Kandahar city. Both Kandahar city and the province of the same name have been major fronts in the Afghan war.
The Taliban assault came a day after the group confirmed the killing of al Qaeda leader Osama bin Laden, slain in a U.S. military raid in Pakistan on Monday.
The militant group, which harbored bin Laden's terror network when it attacked the United States on September 11, 2001, said bin Laden's death will give "new impetus to current Jihad."
Bader, the name of the Taliban's offensive, is a reference to a battle in the early days of Islam, when the Prophet Mohammed is believed to have successfully led a key fight against non-Muslims.
