KARACHI, Pakistan (AP) — From his home off a dirt road cluttered with trash in Pakistan’s teeming city of Karachi, policeman Didar Ahmed’s son shows the bloodstained jacket his father was wearing when gunmen cut him and three colleagues down in a hail of bullets last month.

Ahmed’s brother Gulzar looks at the bullet-riddled garment with a blank stare. He recalled how days before his brother’s death, they had talked about the rising dangers of police work as officers increasingly come under attack by criminal gangs and militants from the Pakistani Taliban.
