CAIRO: Egypt’s interior ministry said on Saturday police arrested 60 people across the country during violent protests the night before targeting government and police buildings.

In Cairo, police arrested 30 people in clashes outside one of the presidential palaces, the ministry said in a statement.

Opposition activists have organised almost weekly protests every Friday which often dissolve into clashes at a presidential palace.

Thousands of supporters of Musi took to the street on Friday to denounce violence after weeks of bloody protests between police and anti-Musi protesters.

The Construction and Development Party had called for the rally under the slogan “Together against violence,” blaming the liberal-led opposition for unrest that has recently swept the country.

The opposition National Salvation Front “is responsible for the violence, they incite the people to hate the Islamists,” said Hamdi Ramadan, 45.

“Their calls for Mursi to leave are going to destroy the country,” said Mohammed Abdel Dayem, 39.

Protesters also called for the release of blind Sheikh Omar Abdel Rahman, holding up pictures of the Egyptian cleric jailed in the Unites States for his role in the 1993 World Trade Center attack.

In a separate development on Saturday the head of Egypt’s holding company for airports and aviation said that Mursi’s son has applied for a job that pays $133 a month starting salary.

Captain Magdi Abdel Hadi dismissed accusations of nepotism and denied reports that the starting monthly salary would be $5,000.

He said on Saturday that Omar Mursi went through regular procedures to apply for the internally advertised job, including passing English and computer exams.

He says the president’s son is still being evaluated for the position, which pays 900 Egyptian pounds, roughly $133 a month.

Hadi says after six months, salaries rise to some 1,200 pounds, or $180 a month.

The $5,000 figure is unheard of for new graduates in Egypt, where the starting salary for a government job can be as low as $75. The official spoke on condition of anonymity because he wasn’t authorized to talk to the media.
