Karachi, Apr 22 (NNN-PTI) Authorities in Pakistan Saturday declared a reward on the heads of four Islamic militants linked to the al-Qaeda, a week after the Crime Investigation Department (CID) issued a red book for the first time in the southern province of Sindh listing the most wanted criminals of the country.

Gholam Mohtaram, the home secretary of Sindh said that Mohammad Wasif alias Javed, Mohammad Obaid alias Naved, Mohammad Faisal alias Qari and Yousuf Ahmed alias Omer were all involved in terrorist activities and sectarian attacks.

"We have issued head money of Rs 300,000 for each of them because their involvement has been found in some recent cases," he said.

The CID red book which is normally a confidential document last week had listed 42 most wanted Islamic militants, separatists and criminals with head money of around 160 million rupees on just 21 of these criminals.

Karachi has been the target of many terrorist and sectarian attacks in the last six years while the rate of street crime has also spiraled up since last year.

Mohtaram said stringent security measures and improved intelligence surveillance had in recent months curbed the activities of Islamic militants also involved in sectarian crimes in the province.

The names of 29 Sunni sects are on the CID list, in addition to eleven Shias linked to Sipah-e-Mohammad. The Sunni sectarian groups include Lashkar-e-Jhangvi (14 names), Harkatul Mujahideen al-Aalmi (2), Harkatul Mujahideen (1), Amjad Farooqui group (2), Jindullah (6).
