APakistan has made a good start in detaining two suspected commanders of last month's coordinated assault on the Indian financial capital of Mumbai, and now it must persevere against the banned Islamic militant group Lashkar-e-Taiba and its network of support.
The arrests of Lashkar operations chief Zaki ur Rehman Lakhvi and his deputy, Zarrar Shah, come amid mounting evidence that extensive planning and training went into the attacks from Pakistan.
President Asif Ali Zardari has promised that anyone involved in the attacks will be tried and punished, and we understand that he faces many obstacles.
Lashkar was founded with the help of the Pakistani military's main intelligence agency, the Inter-Services Intelligence Directorate, to fight Indian rule in Kashmir
Zardari must ensure that the culprits are punished this time, and he must go after their network.
