headlines: Russia is seeking surveillance drones from Iran, a top Biden aide says.
articles: WASHINGTON — President Biden’s national security adviser said on Monday that Russia was seeking hundreds of surveillance drones from Iran, including those capable of firing missiles, to use in the war in Ukraine.
  
  The official, Jake Sullivan, said that it was unclear whether Iran had already sent any of the remotely piloted systems to Russia, but that the United States had information that indicated Iran was preparing to train Russian troops to use them as soon as this month.
  
  “Our information indicates that the Iranian government is preparing to provide Russia with up to several hundred U.A.V.s, including weapons-capable U.A.V.s on an expedited timeline,” Mr. Sullivan told reporters at the White House, referring to unmanned aerial vehicles.
