This is reported on Kuwaiti newspaper Al-Jarida:
The newspaper learned from Palestinian sources that the U.S. contacted Hamas through the United States embassy in Syria.
Condoleezza Rice’s letter “praised” Hamas position of the truce with Israel in the Gaza Strip and Hamas position from the rocket launchers targeting Israeli cities and towns.
The letter comforts Hamas about the United States position from sending Arab forces to Gaza Strip saying hat the U.S. became convinced of the futility of this step.
According to the source, this letter came as an answer to Iran’s letter to Hamas showing Iran’s concerns about Hamas operation targeting the Palestinian Jihadi factions still targeting Israeli cities and towns.
