Kerry warns no deal if Iran talks leave issues unresolved

Washington: US Secretary of State John Kerry warned on Wednesday there would be no nuclear deal if Iran fails to address all the issues left unresolved in their marathon talks.

"It may be that the Iranians will not fill out the full measure of what was agreed on in Lausanne, in which case there will not be an agreement," Kerry told reporters, referring to the parameters of a deal to stop Iran getting a nuclear bomb agreed on April 2 in Switzerland.
