Newspapers in Egypt and the wider Middle East have commented widely on the arrest of former Egyptian President Hosni Mubarak and his sons over allegations of corruption.
Egyptian newspapers praised the decision to detain Mr Mubarak and his sons for 15 days pending investigations by the public prosecutor as a sign that nobody should be above the law following the revolution in the country.
Elsewhere in the Middle East, newspaper editorials said that the arrests should be a lesson for other leaders in the region, while one Iranian newspaper saw the hand of America behind developments in Egypt.

Mubarak's trial for corruption and for embezzled and stolen funds is not enough. Rather, he should be tried for tarnishing Egypt, and also for… the diminishing of its Arab role.

By considering replacing Mubarak, America is forced to sacrifice its allies in order to protect its interests in the region… After the call by the Egyptian revolutionaries for Mubarak's trial turned into a national demand, American politicians are forced to bring another dictator to court against their will.
