US-led troops killed a former high-ranking policeman in a raid near Kabul overnight, officials said Saturday, as four security guards and dozens of rebels died elsewhere in Afghanistan. Mohammada Jan, retired director of traffic police in the province of Logar was killed as US-led troops and Afghan police attacked his house in an overnight raid, provincial police chief Ghulam Mustafah told a foreign news agency. "We had intelligence reports about his sons' involvement in destructive activities but we had no information about him being involved in such activities," Mustafah said. The chief added, however, that the US-led coalition had informed Afghan police that Jan was involved in a suicide truck bombing in the province which killed 25 people on Thursday.
