SEOUL, Aug 6 (Reuters) - North Korea has deployed troops, weapons and now, according to a Ukrainian intelligence official, a missile unit to support Russia's war against Ukraine, marking Pyongyang's most significant involvement in a war since the 1950s.

The Senate voted 86 to 11 to pass the sweeping Russia sanctions bill championed by the late Sen. Lindsey Graham on Friday, advancing legislation that would give the White House more leverage against Moscow as it seeks to end the war in Ukraine — and a brand new tariff tool.
