Hundreds of migrants from Central America moved off a closed border bridge and waded across the Suchiate River at the Guatemala-Mexico border after Mexican officials informed the group they would not be permitted to move farther into the country.

With the river low from the dry season, migrants were able to cross but were met with the Mexico"s National Guard lining the river"s banks on the other side.

The caravan of migrants are now on Mexican territory and are being prevented from transiting through the country by scores of armed Mexican National Guard members, some outfitted in riot gear, who are under orders from government officials to block their entry.

At least 4,000 people who hoped to travel northward to the U.S. entered Guatemala from Honduras last week, according to the Guatemalan government. The migrants threatened to enter by force if authorities refuse to allow that. But now, in Mexico, security officials apparently are not planning to budge.
