SAN MARTIN TEXMELUCAN, Mexico (Reuters) - Hundreds of migrants walking towards Mexico City on Thursday brought traffic to a halt at an important highway connecting the capital and the central state of Puebla, a Reuters witness and a local authority said.
Migrants, many traveling with children, walked between autos and trucks and some even laid down to rest, a Reuters witness said. They had left the San Martin Texmelucan municipality in Puebla earlier on Thursday.
