Masked gunmen on Friday attacked two buses and a truck carrying Coptic Christians in Egypt, killing more than 20 people and wounding dozens, according to officials.
The attackers arrived in three pick-up trucks and opened fire on the vehicles carrying visitors to the Saint Samuel Monastery in the Minya province, about 220km south of the capital, Cairo, before fleeing the scene.
Egyptian security and medical officials told the Associated Press news agency that the death toll in the shooting has risen to 28.
The fatalities include many children, AP reported.
There was no immediate claim of responsibility.
Pictures of a bus at the scene aired by state TV showed its windows shot out.
“They used automatic weapons,” Essam el-Bedawi, Minya governor, told state media.
Security forces launched a hunt for the attackers, setting up dozens of checkpoints and patrols on the desert road.
Following the attack, President Abdel Fattah el-Sisi called for a meeting with security officials.
Egypt’s Christian minority, which makes up about 10 percent of the country’s population, has repeatedly been targeted by armed groups.
