Ishaq, who heads the banned Sunni extremist outfit that is responsbile for attacks on Shia Muslims, was also the alleged mastermind of the attack on the Sri Lankan cricket team in 2009, in which 8 people, all Pakistanis, were killed. 

On Tuesay night, about 15 militants opened fire on a police vehicle carrying Ishaq and his sons, and managed to escape with them on motorycycles, Dawn reported, citing an official from the counter-terrorism department. 

However, the fleeing militants were met with another police party that had been informed of the attack, and a gunfight ensued between them. 
The militants, including Ishaq, were killed in the encounter.
 
Police found several explosives and weapons such as suicide vests, hand grenades, Kalashnikov rifles, pistols and magazines on the militants. 
Lashkar-e-Jhangvi had been banned in 2001 by former President Pervez Musharraf. It is said to be affiliated with the Al Qaeda.
