Mina Changwrote for CNN about violence in Venezuela:
The violence that broke out Wednesday during Venezuela's Independence Day felt all too familiar. In fact, only last week I had seen for myself some of the chaos that has enveloped the country when I visited Caracas.
I was there to meet with local partners who have been begging for help in a humanitarian crisis that is still too often being overlooked. And, as I traveled around the city, I saw suffering and violence -- in plain view -- unlike any I had seen in all my years of working in active war and disaster zones.
