Egypt's health minister Maha El-Rabat has ordered all medical staff to be on call in South Sinai governorate after a bomb blast in Taba on Sunday left at least four dead, Al-Ahram's Arabic news website reported.
The minister also sent 16 doctors and 40 nurses to deliver medical aid at Taba and Nuweiba Central Hospitals, where most of those injured in the blast are being treated.
El-Rabat affirmed she has been in direct contact with the hospitals after the bombing to make sure that enough blood is available on site.
Sunday's attack on a tourist bus in the Red Sea resort town of Taba killed at least four passengers, three South Korean tourists and one Egyptian, and injured 14.
Although Egypt has faced escalating militant attacks on security personnel since the July 2013 ouster of president Mohamed Morsi, Sunday's blast is the first directly targeting civilians.
