Afghan police have killed over a dozen Taliban militants and arrested 11 others during series of operations over the past 24 hours, the Interior Ministry said in a statement released on Thursday.

"Units of police in conjunction with the national army and the NATO-led coalition force during series of cleanup operations in Kabul, Kunduz, Kapisa, Kandahar, Logar, Zabul and Ghazni provinces have killed 15 Taliban militants and arrested 11 others over the past 24 hours," said the statement.

However, it did not say if there were any casualties on the security forces. Taliban militants fighting the government have yet to comment.
