When Andro Naguib Gobrail arrived at Cairo's main thoroughfare, the Corniche, on Sunday, he was on a mission: to pick up his father, Coptic human-rights activist Naguib Gobrail. The elder Gobrail had been shot in the leg when Egyptian soldiers attacked peaceful Christian protesters near the iconic Maspero building, which houses radio and television facilities. "They put a gun over my head, and they asked me to go away," the younger man tells TIME. "I carried my dad to my car. When I got there, I found a lot of people saying, 'We will kill you.' "
The Gobrails quickly left the area — but not before witnessing part of the rampage that by late Monday had left at least 24 dead and 270 injured, according to the Egyptian Health Ministry. Many were mowed down by vehicles driven by soldiers under the command of the Supreme Council of the Armed Forces (SCAF), the interim body ruling Egypt. According to Andro Naguib Gobrail, the cars deliberately plowed through crowds of protesters. "The army was driving over the bodies," Gobrail says. "It was disturbing." He says he later went to the nearby Coptic hospital on Ramses Street — which became a gathering place for survivors and members of the Christian community — and saw one corpse with 10 bullet wounds to the chest.
