Publicity, transport, food: migrants flock to more caravans after Trump broadsides

For years, an annual caravan of Central American migrants travelling 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. Though only a fraction of the 1,500 migrants made it to the United States, coverage of their trek in vehicles and on foot inspired many considering the journey to see caravans as a safer way to travel than the perilous trip many had for years undertaken alone, dozens of migrants told Reuters.

Trump says Saudis staged 'worst cover-up ever' on Khashoggi; the U.S. revokes visas of some Saudis

President Donald Trump said on Tuesday Saudi authorities staged the "worst cover-up ever" in the killing of prominent journalist Jamal Khashoggi this month, as the United States vowed to revoke the visas of some of those believed to be responsible. Trump spoke hours after Turkey's president, Tayyip Erdogan, dismissed Saudi efforts to blame Khashoggi's death on rogue operatives. Erdogan urged Riyadh to search "from top to bottom" to uncover those behind Khashoggi's death in the Saudi consulate in Istanbul on Oct. 2, an incident that has sparked global outrage and strained relations between Riyadh and Washington.
