KYIV (Reuters) - Ukraine does not plan to use multiple-launch rocket systems it receives from the United States to attack facilities in Russia, a Ukrainian presidential advisor said on Friday.

       "Ukraine is waging a defensive war and does not plan to use the MLRS to attack facilities in Russia," Mykhailo Podolyak said in a Twitter post. "Our partners know where their weapons are used."
