Hours of talks aimed at de-escalating fighting between Israel and Iran failed to produce a diplomatic breakthrough as the war entered its second week with a fresh round of strikes between the two adversaries.

The first face-to-face meeting between Western and Iranian officials in the weeklong war concluded after four hours with no sign of an immediate breakthrough.

President Donald Trump will decide in the next two weeks whether the U.S. will get involved in the Israel-Iran air war, the White House said on Thursday, raising pressure on Tehran to come to the negotiating table.
