According to the interior ministry, how many generals are to end their service?

The Egyptian government says more than 600 senior police officers are being removed from their jobs. Their dismissal has been a key demand of protesters, who believe the officers were involved in the killing of hundreds of people during the uprising against Hosni Mubarak earlier this year. From Cairo, Jon Leyne reports.
    With protests in Tahrir Square being stepped up daily, the interior ministry has announced a major purge of officers. Five hundred and five generals and 160 other officers are to end their service. According to the interior minister, 18 of the generals are accused of having a role in the killing of protesters during the revolution earlier this year. It’s not been specified whether the officers are being sacked or just retired early.
