Gunmen attacked security forces near St. Catherine’s Monastery in Egypt’s south Sinai on Tuesday, killing at least one police officer and injuring four others, the Health Ministry said, just a week after two deadly church bombings killed 45.

Islamic State claimed responsibility for the attack on a police checkpoint about 800 meters (yards) from the entrance to the monastery, one of the world’s most important Christian sites.

The attack comes just 10 days before Pope Francis is scheduled to visit Egypt and just over a week after two deadly suicide bombings on Christian churches, also claimed by Islamic State, plunged the country into mourning and marked one of the bloodiest days for the country’s Christian minority in decades.

St. Catherine’s, founded in the 6th century and located at the foot of Mount Sinai, is one of the oldest Christian monasteries in the world and a UNESCO world heritage site. It is part of the Eastern Orthodox church.

Egypt’s Christian minority, which makes up about 10 percent of the country’s 92 million people, has increasingly been targeted by Islamist militants, with three deadly church attacks in the span of four months.
