Former Alaska Gov. Sarah Palin visited a Jewish holy site in Jerusalem soon after arriving in Israel Sunday on a trip that has raised speculation she is honing her foreign policy credentials before a run for the U.S. presidency next year.

Palin arrived in Israel Sunday after visiting India.

Palin, who was John McCain's running mate in his failed 2008 campaign for president, rarely travels abroad and has been criticized for a weak foreign policy record.

Palin did not comment to Israeli reporters at the airport and was whisked away in a white van.

Although the trip is private, she is to meet with Prime Minister Benjamin Netanyahu on Monday.

"As the world confronts sweeping changes and new realities, I look forward to meeting with Prime Minister Netanyahu to discuss the key issues facing his country, our ally Israel," Palin said in a statement.

Palin toured holy sites in Jerusalem's Old City Sunday evening.

She visited the Western Wall, a retaining wall of the compound where the biblical temples stood 2,000 years ago and which is now the holiest place where Jews can pray.

The Al-Aqsa Mosque compound, Islam's third-holiest site, was built in the seventh century atop the ruins.

Palin returns to the U.S. Tuesday.
