An Egyptian health official says there is no “scientific” proof that former President Hosni Mubarak is suffering from cancer while awaiting trial on charges of corruption and ordering the killings of opposition protesters.

Mr. Mubarak's lawyer said last week the deposed leader has stomach cancer with growing tumors. But, Egyptian media published reports Sunday quoting health ministry official Abdel-Hamid Abaza as saying the government has no scientific document to confirm the cancer claim.

Egyptian newspaper Al-Masry al-Youm says a German medical team was due to examine Mr. Mubarak later Sunday for signs of cancer. It says the team includes the German surgeon who operated on the ousted president last year to remove his gallbladder and part of his pancreas, which were cancerous.

Mr. Mubarak has been detained in a hospital in the Red Sea resort of Sharm el-Sheikh since suffering heart problems during questioning on April 13.

The 83-year-old handed power to a military council in February after almost 30 years in power, under pressure from an 18-day popular uprising against his autocratic rule. He faces trial in early August on charges of corruption and ordering the killings of hundreds of protesters during the revolt.

Mr. Mubarak's interior minister Habib el-Adly and six other former officials already are on trial in connection with the killings. A Cairo court resumed the trial Sunday, but dozens of relatives of those killed rallied outside, some chanting slogans against el-Adly and others throwing rocks at police. The court later adjourned the trial until July 25.
