Exactly a year ago on a terrible July evening in just a span of 10 minutes, Mumbai's lifeline was snapped. Seven blasts ripped through the city's western railway line network. Over 180 people died and hundreds more were injured. Today we look back at the day of terror that has left a trail of painful memories. The first blast occurred between Khar and Santacruz railway stations at 6.24 pm, in the first class men's compartment.
