Anthrax parcel sent to Pakistan PM's house: police

Pakistani police were Wednesday investigating how and why a parcel containing anthrax was sent to the prime minister's official residence in the capital Islamabad last month.

"The parcel containing anthrax powder was sent last month, about 20 days ago. After the laboratory test confirmed that the parcel contained anthrax we registered a case against unknown people," said police officer Hakim Khan.
