Tapachula, Mexico (CNN)A chaotic scene unfolded as a massive caravan of Honduran migrants reached the Guatemala-Mexico border Friday.
A surge of migrants broke through a steel fence that had been padlocked shut. Mexican police in riot gear pushed them back, setting off smoke canisters. Hundreds of Mexican Federal Police sealed the border as drones and helicopters hovered above the crowd, which waited on a bridge in sweltering heat.Thousands of migrants are waiting to cross, according to CNN teams at the scene. At least a dozen migrants stuck on the bridge have jumped into the river below.

The migrants who remained told CNN they joined the caravan because they had no other choice, noting that they were desperate for work. Mexican officials had said people seeking asylum would be processed at the border. But it’s unclear what will happen next. Members of the group — many with children in tow — had cheered and chanted as they streamed toward the port of entry, with celebratory airhorns blaring.
