The Supreme Court will hear today the plea by 1993 Mumbai bomb blasts convict Yakub Memon, who has sought a stay of his death sentence set for 30th of this month. After the Apex Court had on 21st July rejected his mercy petition, Memon moved the Supreme Court contending that the death warrant for his execution was issued before he could have exhausted the legal remedies available to him. He also sought that his death sentence be stayed by the Apex Court. Memon had also filed a mercy petition before the Maharashtra Governor seeking commutation of his death sentence to life imprisonment.<br/><br/>The blasts on March 12, 1993, ripped through Mumbai killing at least 257 people at separate landmarks, including the Bombay Stock Exchange. According to the CBI, Memon's brother Tiger Memon and underworld don Dawood Ibrahim were the main masterminds behind the attack. Memon is the only convict to be sentenced to the gallows for his role in the serial blasts. The Supreme Court had commuted other 10 convicts' sentence from death to rigorous life imprisonment.
