Reuters - Iran summoned a Swiss envoy for a second time on Friday to deliver its answer to a U.S. message, Iranian state media said, hours after a Swiss diplomat delivered Washington�s communication over the killing of Iranian Quds force chief Qassem Soleimani.

The Swiss envoy representing U.S. interests in Tehran was summoned to the foreign ministry to receive the �proper� answer from Tehran, ministry spokesman Abbas Mousavi told state news agency IRNA, without giving further details.
