Pompeo warned Lavrov against U.S. soldier bounties

"If the Russians are offering money to kill Americans, or for that matter other Westerns as well, there will be an enormous price to pay. That's what I shared with Foreign Minister Lavrov," Pompeo said.

The New York Times in June reported that a Russian military intelligence unit secretly offered bounties to Taliban-linked militants for killing coalition forces in Afghanistan - including American troops, citing U.S. intelligence officials.

President Donald Trump said he was not told about the information because many U.S. intelligence officials doubted its veracity, although several U.S. and European sources contradicted his comments.
