Moments after the explosion rocked her church, Mona Faiez's phone rang. It was her sister, checking to see if she was alive.
She was unhurt; she wasn't at the church, where 27 now lay dead and scores more were injured. But alerted by the call, she rushed toward it. These were her fellow parishioners, her closest friends.
"What kind of human could do this," she asked, "and why?" Less than three hours later, a suicide bomber detonated his explosives at the entrance to St Mark's Cathedral in the northern city of Alexandria, killing 17 and injuring many more. The dead included three police officers who stopped the bomber from entering the site. The head of Egypt's Coptic Church, Pope Tawadros II, was presiding over Palm Sunday Mass at the church, also packed with worshipers, but he was unharmed.
President Abdel-fatah al-Sisi had declared a state of emergency across the country for three months.
Altogether, at least 44 people died and more than a hundred were injured in the two attacks, the deadliest single day to strike Egypt's Coptic Christian minority in decades.
