WASHINGTON (Reuters) -- New US Defense Secretary Chuck Hagel, whom Republican critics have sought to portray as anti-Israel, will meet Israeli Defense Minister Ehud Barak at the Pentagon on Tuesday for his first face-to-face visit with a foreign counterpart.

A US official, speaking on condition of anonymity, said the talks between the US and Israeli defense chiefs would include discussions on Iran, but did not offer details.

"The secretary is honored that Minister Barak will be the first foreign counterpart that he will host at the Pentagon," the official said, adding the two had known each other for more than a decade.

Barak's visit to the Pentagon coincides with a conference from Sunday to Tuesday of the leading US pro-Israel lobbying group, the American Israel Public Affairs Committee, or AIPAC, at which Barak, a former Israeli prime minister, is scheduled to speak.

Hagel was put on the defensive during his Senate confirmation hearing for once accusing a "Jewish lobby" of intimidating people in Washington, comments the former two-term Republican senator has repeatedly said he regretted.

Hagel, a decorated Vietnam War veteran, has spoken strongly about America's close defense ties with Israel and the need to prevent Iran from obtaining a nuclear weapon. Iran says its nuclear program is entirely peaceful.
