A 7.3-magnitude earthquake hit Nepal on Tuesday, killing dozens of people and triggering renewed panic on the devastated streets of Kathmandu.
The temblor came less than three weeks after 8,000 people died when a 7.8-magnitude quake rocked the Himalayan country on April 25.
"It was completely unexpected," 21-year-old nursing student Shristi Mainali told NBC News from Kathmandu.
