U.S. Senate votes overwhelmingly for tougher North Korea sanctions

WASHINGTON (Reuters) - The U.S. Senate voted unanimously on Wednesday to toughen sanctions on North Korea over its nuclear program, human rights record and cyber activities, as U.S. lawmakers sought to crack down on Pyongyang for its nuclear tests.

The House of Representatives passed a similar bill last month. Differences between the two are expected to be resolved quickly and Senate Democrats said they expected President Barack Obama would sign the measure into law.
