The targeted killings are part of a spate of similar attacks on those associated with the government, further complicating efforts by international forces in country to hand over security responsibility to Afghans as foreign combat troops withdraw.
In the first attack, a bomb hidden in a cemetery in the southern province of Helmand killed a police chief and his brother who were visiting a family grave for the Eid al-Fitr holiday.
Seven of the men’s family members were wounded in the early morning blast in the provincial capital of Lashkar Gah, said Helmand Deputy Police Chief Ghulam Rabbani.
No one immediately took responsibility, but the attack was consistent with the Taliban’s strategy to target authorities and others who align themselves with the government or international forces.
The two men were brothers of a lawmaker for Helmand province, Abdulwadood Popal, who was not at the cemetery at the time of the blast. The family was visiting the grave after morning prayers for the holiday, which ends the month-long Ramadan fasting period.
In Farah province in the west, gunmen on a motorcycle opened fire on the car of an intelligence service official as he was driving home from a family visit, killing him and his brother who worked for the customs service. Another relative was wounded, provincial deputy police Chief Ghulam Ghows Malyar added.
Meanwhile in the east, NATO forces said that three international service members were killed in a bomb attack, without providing further details.
At least 41 international troops have been killed so far this month in Afghanistan.
In a speech marking the holiday, President Hamid Karzai condemned the repeated insurgent attacks during Ramadan.
“The enemies of Muslims during the holy month of Ramadan treated the nation of Afghanistan cruelly: bombs, explosions in mosques, suicide attacks in mosques,” Mr. Karzai said.
If the Taliban were not responsible for such attacks, he said, they must disavow them. “If you are not behind this, it is being done in your name. As Muslims, as Afghans, raise your voice and say that you did not do it,” he appealed.
In a message ahead of Eid al-Fitr, Taliban leader Mullah Mohammad Omar instructed his fighters once again to avoid killing or wounding Afghan civilians.
“Employ tactics that do not cause harm to the life and property of the common countrymen,” he said in an eight-page message released to news organizations last week. The Taliban previously have said, however, that they do not consider those who collaborate with the government to be civilians.
