Powerful 6.7 magnitude aftershock rattles Nepal as aid arrives in region

A powerful magnitude 6.7 aftershock shook the Kathmandu region of Nepal sending people yelling and running Sunday, a day after a massive earthquake crippled the region killing more than 2,200.

The U.S. Geological Survey said the aftershock registered at a shallow depth of six miles.

"The aftershocks keep coming ... so people don't know what to expect," said Sanjay Karki, Nepal country head for global aid agency Mercy Corps. "All the open spaces in Kathmandu are packed with people who are camping outdoors. When the aftershocks come you cannot imagine the fear. You can hear women and children crying."
