The United States today asked Pakistan to follow through its commitment to bring the perpetrators of 2008 Mumbai attack to justice after a court ordered to release Lashkar-e-Tayiba operations commander Zaki-ur Rehman Lakhvi.

"The government of Pakistan has pledged its cooperation in bringing the perpetrators -- financiers, and sponsors of the Mumbai terrorist attacks to justice and we urge Pakistan to follow through on that commitment," the State Department Spokesperson, Jen Psaki, told reporters at her daily news conference.

"We are monitoring reports that an Islamabad high court judge suspended detention orders for the alleged Mumbai attack mastermind," she said. "For now he remains in prison," Psaki, told reporters at her daily news conference.

She said, "Pakistan is a critical partner in a fight against terrorism. We've certainly seen these reports (of a court granting bail to Lakhvi), but we can't speculate on the outcome of an ongoing legal process."

Islamabad high court today suspended the detention order of 2008 Mumbai terror attack mastermind Lakhvi and ordered his immediate release, drawing India's ire.
