April 6 (Reuters) - Iran's Revolutionary Guards stopped two Qatari liquefied natural gas tankers headed toward the Strait of Hormuz earlier on Monday before transit and ordered them to hold position without explanation, a source briefed on an Iran-U.S. agreement to allow the tankers to transit told Reuters.
The source said the tankers had been listed as among those Iran would allow to transit under an Iran-U.S. agreement reached last week via Pakistan.
