US Ambassador to India Nancy J Powell's resignation is not related to any tension or any recent situation, the Obama administration asserted today refuting all such media reports in this regard.

"It is in no way related to any tension, any recent situations. There's no big behind the scenes story here," State Department Deputy Spokesperson Marie Harf told reporters when asked about Powell's announcement in New Delhi that she has sent her resignation to President Barack Obama.

"She announced today that she has submitted her resignation to President Obama, as has been planned for some time, and she will retire to her home in Delaware before the end of May," Harf said.
