A Pakistani immigrant was sentenced to 30 years in prison for hatching an unsuccessful plot to blow up a busy Manhattan subway station as revenge for wartime abuses of Iraqis.

Shahawar Matin Siraj, 24, was arrested on August 27, 2004, on the eve of the Republican National Convention. Though there was no proof he ever obtained explosives or was linked to any terror organizations, prosecutors said his intentions were ominous: He wanted to blow up the Herald Square subway station, a bustling transportation hub.

Siraj showed no reaction as the sentence was read on Monday. He faces deportation when his sentence is completed.

‘‘I apologize for all the stuff I said on those tapes,’‘ Siraj said before he was sentenced. ‘‘I’m taking responsibility for 34th Street, but I was manipulated by this person.’‘
