A defense lawyer says a Pakistani court has ordered the release of the main suspect in the 2008 Mumbai attacks for the second time in less than a month.

A March 13 verdict also ordered the release of Zaki-ur-Rehman Lakhvi, but he remained in detention as Pakistan faces mounting pressure to more actively confront Islamic militants.

His defense lawyer, Rizwan Abbasi, says he is still in custody.

Lakhvi, one of seven suspects being tried in Pakistan in connection with the attacks that killed 166 people, has been in jail since his arrest in 2009.

India has repeatedly urged Pakistan to more actively pursue the case, and Pakistan faced renewed pressure following the Taliban attack on a school in Peshawar in December, which left more than 140 people dead, mainly schoolchildren.
