A magnitude 6.1 aftershock struck Haiti Wednesday morning. Its epicenter was 36 miles west-southwest of Port-au-Prince and was felt across the island, the United States Geological Survey said.
The jolt, the strongest since the 7.0 magnitude earthquake on Jan. 12, rattled buildings and sent people screaming into the streets throughout the capital.
The largest contingent of medical aid and supplies was due to arrive today aboard the Navy hospital ship USNS Comfort.
