National Conference patriarch on Tuesday welcomed US President Donald Trump's claim that Prime Minister Narendra Modi had sought United States's in resolving the Kashmir dispute.

"It is a matter of happiness that when PM Modi talked to Trump he had told him that Kashmir issue is complex & if there can be some help it would be good. I congratulate Modi ji, he too wants to use everything to solve this issue that is creating tensions between India & Pakistan," Farooq Abdullah said.

US President Donald Trump on Monday offered to be the "mediator" between the two countries on the Kashmir issue as he met Prime Minister Imran Khan at the White House for the first time.

Trump said that he is ready to help, if the two countries ask.

However, India on Monday denied Trump's claim that PM Modi had asked him to mediate in resolving the Kashmir issue with Pakistan.

External Affairs Ministry Spokesperson Raveesh Kumar tweeted, "We have seen @POTUS's remarks to the press that he is ready to mediate, if requested by India & Pakistan, on Kashmir issue. No such request has been made by PM @narendramodi to US President."

The allegation by Donald Trump drew sharp criticism from Opposition as they demanded a clarification from the government. Several Opposition leaders, including Congress's Shashi Tharoor and National Congress chief and Farooq Abdullah's son Omar Abdullah, raised doubts on the validity of Trump's statement.

"Personally I think @realDonaldTrump is talking out of his hat when he says @PMOIndia asked for US involvement in solving the Kashmir issue but I'd like to see @MEAIndia call Trump out on his claim," Omar Abdullah tweeted.

In his tweet, Shashi Tharoor said, "I honestly don't think Trump has the slightest idea of what he's talking about. He has either not been briefed or not understood what (Prime Minister) Modi was saying or what India's position is on 3rd-party mediation. That said, MEA should clarify that Delhi has never sought his intercession."

India maintains that the Kashmir issue is a bilateral one and no third party has any role.

India has not been engaging with Pakistan since an attack on the Air Force base at Pathankot in January of 2016 by Pakistan-based terrorists, maintaining that talks and terror cannot go together.
