Democratic presidential aspirant Barack Obama is in Israel today, as he seeks to win over the wavering Jewish vote back home in the United States.
The presumptive nominee, who will take on Republican rival John McCain this autumn, is visiting Israel on a diplomatic trip to the Middle East and Europe which has also seen him visit Iraq, Jordan and Afghanistan.
He will visit the town of Sderot which has suffered under a hail of missiles fired from the Hamas-controlled Gaza Strip in recent months.
It follows a similar visit by Mr McCain back in March soon after the Republican favourite emerged as the dominant force in his party.
Mr Obama has been at pains to back Israel and in a speech last month emphasised his commitment to working towards a two-state solution "living side by side in peace and security".
A statement to reporters issued before his visit to Israel, only his second ever, said: "Israel is a strong and close friend of the United States, and is confronting grave threats from Gaza to Tehran."
Concerns over Iran's plans to develop civil nuclear energy will dominate Mr Obama's trip. Israel and Iran are threatening mutual military action if the Iranians do not cease what many in the international community is a covert effort to develop a nuclear weapon.
"The danger from Iran is grave; it is real; and my goal will be to eliminate this threat. I will always keep the threat of military action on the table to defend our security and our ally, Israel," he said in Washington last month.
Mr McCain has made clear he will also act to ensure Iran does not develop nuclear weapons. Speaking from the US on the eve of Mr Obama's trip, he said: "I have to look you in the eye and tell you that the United States of America can never allow a second Holocaust."
