Qatar and the U.S. on Tuesday struck a pact to strengthen Qatari action against terrorist funding, an issue at the center of the diplomatic crisis in the Gulf that has pit longstanding American allies against each other.
The memorandum of understanding was signed as Secretary of State Rex Tillerson was in the Qatari capital, Doha, part of his sweep through the region in pursuit of a negotiated settlement of the feud, now in its second month. With the accord, the U.S. and Qatar will do more to track down funding sources, will do more to collaborate and share information and will do more to keep the region and our homeland safe, Tillerson told a news conference in Doha.
