Egyptian President Hosni Mubarak will travel to Germany for further medical treatment only four months after he underwent surgery there, Lebanese newspaper As-Saffir reported Tuesday.

Mubarak’s health has taken a serious turn for the worse, with fears that the 83-year-old is suffering from cancer, Haaretz learned last week.

Mubarak made a surprise visit to Paris last Monday for meetings with French President Nicolas Sarkozy and Lebanese Prime Minister Saad Hariri - but he also underwent a round of medical tests, prompting speculation that these were the real reason for the visit.

According to the report in As-Saffir, Mubarak will be absent from Egypt for approximately 10 days.

Due to Mubarak's upcoming trip to Munich, Prime Minister Benjamin Netanyahu's meeting with the Egyptian president has been postponed for a second time and will take place on Sunday, an Israeli official said. Mubarak has also reportedly canceled meetings with Palestinian President Mahmoud Abbas.

Netanyahu originally announced he would meet Mubarak in Cairo on Tuesday to discuss efforts to restart direct peace negotiations between Israel and the Palestinians.

The session was subsequently reset for Wednesday, and its location moved to Egypt's Red Sea resort of Sharm el-Sheikh, due to what Israel said were changes in Mubarak's schedule. The official cited "logistical reasons" for the further delay, to July 18, without elaborating.

Egypt was the first of two Arab states to sign peace treaties with Israel, and Mubarak has been active in helping to mediate between Israel and the Palestinians.
