KABUL, Sept 27 (AFP) - A bomb exploded in the Afghan capital late Monday, just days ahead of the country's landmark presidential elections, but caused no injuries, officials said.
"There was a small bomb explosion in the 11th police district by the main road but luckily (we) had no casualties," Kabul police chief General Baba Jan said.
The explosion hit some two metres from a local police post and the blast broke the windows of surrounding shops.
"It was just next to the police post," Baba Jan said, adding that six people had been detained for questioning over the incident.
"I heard a loud blast and didn't understand what it was, but thank god it was late and the street was empty," said Ahmmand Zaman, a pharmacist whose shop windows were shattered by the blast.
Officials said it too early to say who was responsible for the blast but militants with the ousted fundamentalist Taliban regime have claimed similar attacks in the past.
"It is soon to say Taliban are behind it but it was an act by the enemies of our country who want to sabotage the election," said a source close to the Ministry of Interior.
Afghans will go to the polls on October 9 to choose their president in the first elections to be held since the ousting of the Taliban by a US-led offensive in late 2001.
Security has been deteriorating ahead of the elections while Taliban militants have pledged to disrupt polls and vowed to attack all 18 presidential candidates. They have claimed responsibility for a rocket attack which missed President Karzai's helicopter earlier this month.
Remnants of the ousted Taliban regime have also claimed responsibility for five rockets which were fired over the Afghan capital injuring two people on September 9.
Three Americans and at least six others were killed in an attack on US security firm Dyncorp in Kabul on August 29.
