Israeli Prime Minister Ehud Olmert and Palestinian Authority President Mahmoud Abbas are expected to meet at an international gathering in Jordan this week.
Jordanian officials say the two will attend a breakfast Thursday hosted by Jordan's King Abdullah as part of a forum for Nobel laureates in Petra.
It would be the first meeting between the Israeli and Palestinian leaders since Mr. Olmert took office last month.
In the latest violence, witnesses say an Israeli airstrike wounded at least four people at the Jebaliya refugee camp in Gaza City. Israeli has not commented on the report. Israel often uses airstrikes against suspected Palestinian militants.
Meanwhile, residents of the Israeli town of Sderot are staging protests to demand a stronger Israeli response to rocket attacks by Palestinian militants in Gaza.
Israeli officials say Palestinian militants have fired about 130 rockets at Sderot in the past 10 days. The rocket attacks rarely cause deaths or heavy damage.
