TOPSHOT - A person who trekked for over a month across Central America and Mexico within a caravan of Central American migrants, mostly Hondurans, in the hopes of reaching the United States, draws on a window after boarding a bus to be taken to a new shelter after heavy rain in Tijuana, Baja California State, Mexico, near the border with the US, on November 29, 2018. - Members of the Central American migrant caravan are starting to lose hope, and in some cases are turning back after more than a month's trek. Their surprise bid to rush the border en masse on Sunday ended as abruptly as it began, when US Border Patrol agents fired tear gas and rubber bullets to force them back. (Photo by Pedro PARDO / AFP)
