TEHRAN, May 5. /TASS/. The United States has stepped up its efforts to establish contact with Iran, using a number of third countries as intermediaries, not just Pakistan, the Tasnim news agency reported, citing a source.

According to the source, several days ago some members of the American negotiating team began attempts to intensify dialogue with Tehran via other countries, apart from Pakistan.
