Karachi: Police in Pakistan's commercial capital Karachi have reportedly launched a hunt for at least 20 rich and bored wives accused of funding the Islamic State of Iraq and the Levant (ISIL) attacks and arranging wives for its followers.

A report appearing in Al Jazeera quoted security officials, as saying that the search was launched after police arrested one suspect who they believed had financed a gun attack on a bus carrying Pakistani Shias that killed 44 people in May. It was the first attack claimed by ISIL inside Pakistan.
