The execution of an Iranian Kurdish student, which was supposed to be carried out on Sunday, has been postponed, the student's lawyer told ISNA news agency.

'My client was scheduled to be executed this morning but it was not carried out in order to allocate more time to further investigate the case,' his lawyer Nemat Ahmadi told ISNA.

Habib Latifi, an alleged member of the Party of Free Life of Kurdistan (PJAK), was sentenced to death in 2008. An appeal court upheld the verdict in 2009.

Just before the scheduled execution, Ahmadi had once again written a letter to the head of the judiciary, Sadeq Larijani, asking for the sentence to be revised.

The execution was eventually postponed and Latifi allowed to meet his family members, the lawyer added.

At least 12 Kurds, all reportedly members of PJAK, are on death row after being found guilty of armed confrontation with Iranian forces.
