(Adds Belarus opposition leader testimony) WASHINGTON, June 9 (Reuters) - Belarussian President Alexander Lukashenko no longer is in a position to have influence over Russian military actions in his country because of his dependence on Moscow, U.S. Ambassador to Belarus Julie Fisher said on Wednesday. Russia and Belarus are planning a record number of military exercises this year, according to some experts. The defense ministries have signed a five-year strategic partnership agreement and there have been reports that the two countries are planning to open three new joint military bases. "It is Lukashenko, his willingness to increase dependency on Russia in every possible sphere, that has brought him to the point of being in no position, really, to barely have a say in what it is Russia would decide to do militarily," Fisher told the Senate Foreign Relations Committee.
