RIYADH: Fourteen out of the planned 20 ambulances provided by Saudi aid agency KSrelief are en route to the Gaza Strip via the Rafah border crossing, the Saudi Press Agency reported on Thursday.  The ambulances are carrying crucial medical supplies including biometric devices, oxygen devices, first aid kits, burn treatment kits, transport beds, splints and straps. Rafah, overseen by Egypt, is the only crossing into Gaza not controlled by Israel. KSrelief has finalized four cooperation agreements with international organizations to provide relief worth $40 million for Palestinians in Gaza. On Thursday, the 24th Saudi relief plane departed from King Khalid International Airport in Riyadh to Al-Arish International Airport in Egypt. On board the plane are 31 tons of aid supplies, including food, shelter and medical provisions.  This initiative is part of an ongoing campaign dedicated to alleviating the suffering of Palestinians in Gaza.
