CAIRO (Reuters) - Egypt has tightened control of crossings from the Sinai peninsula and continued assaults on militants after an Islamist group based there said it tried to kill the interior minister in Cairo last week, the state news agency reported on Monday.
The group Ansar Bayt al-Maqdis claimed responsibility on Sunday for Thursday's suicide bombing aimed at Interior Minister Mohamed Ibrahim. It promised more attacks in revenge for a crackdown on Egypt's Islamists, raising fears that militant violence in Sinai could spread across the country.
