For years, an annual caravan of Central American migrants traveling through Mexico to the U.S. border received modest publicity until President Donald Trump condemned it in April, pitching the procession into the glare of the world's media - and into the homes of thousands of potential migrants.

Hundreds of people in a caravan of migrants that crossed from Honduras into Guatemala staged a dramatic bid to breach the Mexican border on Friday, as local governments began preparing to disperse the convoy under pressure from Washington.

The organizer of a migrant caravan from Honduras was detained in Guatemala on Tuesday as the U.S. government threatened to withdraw aid from both countries and El Salvador if the flow of migrants north to the United States was not stopped.

Up to 3,000 migrants crossed from Honduras into Guatemala on Monday on a trek northward, after a standoff with police in riot gear and warnings from Washington that migrants should not try to enter the United States illegally.

More than 1,000 people, including families and women carrying babies, set off from Honduras toward the United States on Saturday, days after the United States urged Honduras' president to halt mass migration.

The president of Honduras said on Monday cuts in U.S. support for Central America would hinder efforts to stem illegal immigration as he welcomed China's growing diplomatic presence in the region as an "opportunity."

About 1,400 children of some 2,500 separated from their parents at the U.S.-Mexican border have been reunited with their families, the U.S. government said in a court filing on Thursday.

Officials from El Salvador, Guatemala, Honduras and Mexico on Thursday called on the United States to provide more details on migrant children still separated from their parents.

Ten days after being separated from his 11-year-old son Eduardo by U.S. immigration officials, Douglas Almendarez was put on a plane back to Honduras, he says, with a promise he would be reunited with his son there.

During their detention last month in a U.S. Customs and Border Protection facility in Laredo, Texas, Karen and her two young sons were constantly cold. The family, which fled violence in Honduras, slept on a hard floor in a holding cell without mattresses, she said, their clothes still wet from crossing the Rio Grande.
