General Martin Dempsey, chairman of the Joint Chiefs of Staff, will meet in Israel with his counterpart Benny Gantz to discuss advances in Iran's nuclear program, which Israel regards as an "existential threat."
"In Israel, the chairman expects to discuss the United States' unwavering commitment to Israel's security, including potential threats from Iran, the ongoing civil war in Syria, and uncertainty in the Sinai," his office said in a statement.
The exact dates of the visit were not disclosed but his office said he would leave Washington over the weekend.
Dempsey's visit comes just days after the inauguration of Iran's new President Hassan Rowhani, who has called for "serious" talks on Iran's nuclear program without delay.
Israeli Prime Minister Benjamin Netanyahu, meanwhile, yesterday pressed the United States to step up pressure on Tehran, warning that otherwise it "will go all the way" and develop nuclear weapons.
Instability in the Sinai is also expected to figure in Dempsey's talks in Israel. Attacks by Islamist militants have increased there since the overthrow of Egyptian president Mohammed Morsi.
In Syria, the US administration promised in June to increase military aid to the rebels, after accusing the regime of President Bashar al-Assad of using chemical weapons.
Dempsey, however, has been reticent about deepening the US military involvement in the conflict, and since March 2011 Washington has limited itself to non-lethal support for the rebels and humanitarian aid.
