Kabul, Afghanistan (CNN) -- Ten people were killed in separate bomb attacks in Afghanistan Tuesday morning, government officials said.
One bombing occurred in Lashkar Gah, the capital of Helmand province, said Daoud Ahmadi, the spokesman for the provincial governor. The explosive device, that was concealed on a bicycle, exploded in a bus station. A woman and child were among the eight killed and 16 wounded, Ahmadi said.
The attack occurred in the same province where NATO troops have launched an offensive against the Taliban. Ahmadi said the attack could have been related to military offensive in Marjah, about 15 miles to the southwest of Lashkar Gah.
"The enemy want to distract attention away from Marjah where they have been defeated," the governor's spokesman said.
The other attack occurred in the eastern Afghanistan province of Nangarhar, according to an Interior Ministry statement.
A bomb on a covered motorcycle exploded when a police convoy was passing by. Two people were killed and two were wounded in the attack, the statement said.
It was unclear if the victims were police officers or civilians.
