U2’s front-man Bono caught Israeli music fans and paparazzi off-guard when he dined at a popular restaurant in the Jaffa Port on Monday (April 9).

Local media reports cited today that the musician, also known as Paul David Hewson, is in Israel on a private visit.

Some reports linked Bono’s visit to business ventures – both he and The Edge are investors in the Dropbox company — which has ties with an Israeli high-tech firm. Others cited that Bono – known as a leading human rights activist — may be in town for an international peace conference.

The singer has visited Israel before. His band played a concert in Tel Aviv in 1997.
