Afghan police officials says at least 10 police officers have been killed in an apparent suicide car bombing in Lashkar Gah, the capital of southern Helmand Province.
Haji Marjan, the police chief of Nad Ali district, said that four civilians were also killed and that the death toll from the October 10 attack is likely to rise.
Afghan Interior Ministry spokesman Sediq Sediqqi said the Taliban also launched a large-scale attack on the security checkpoints in Lashkar Gah.
Sediqqi added that the Afghan security forces "will soon push them back."
The Taliban has been on the outskirts of Lashkar Gah for months as part of its march across Helmand, where most of the world's opium is produced.
Provincial officials have said the Taliban now controls 85 percent of the province, while only a year ago, the government controlled 80 percent.
