Having been in Kolkata several times over the past 5 to 6 years, I recognized the city from the photos before I read the location of this disaster. http://www.foxnews.com/world/2016/03/31/rescue-crews-frantically-se...
This is a tragedy with many people crushed under the collapsed roadway. Kolkata is a crowded city and there are many street people either walking or living in shanties under the roadways.
I've reached out to my friends and colleagues who live in Kolkata and fortunately they are all safe and sound.
