Officials say a roadside bomb has killed two police officers in Eastern Afghanistan, while an overnight gun battle between police and the Taliban in the north left five insurgents dead. The police officers died Saturday when their vehicle hit a bomb near Khost city, the capital of the province of the same name. Deputy provincial Gov. Tahir Khan Sabari says three other officers were wounded. The Associated Press quoted Police as saying that a separate blast in the eastern city of Jalalabad on Saturday injured employees of the country's intelligence agency, but there were no deaths. Meanwhile, Taliban attacked a police checkpoint in northern Kunduz province Friday night. Provincial spokesman Ahmad Sami Yawar says five insurgents died in the fighting, but no police were killed.
