The exact number of Arab casualties is unknown. One estimate places the Arab death toll at 7,000, including 3,000 Palestinians, 2,000 Egyptians, 1,000 Jordanians, and 1,000 Syrians. In 1958, Palestinian historian Aref al-Aref calculated that the Arab armies combined losses amounted to 3,700, with Egypt losing 961 regular and 200 irregular soldiers and Jordan losing 362 regulars and 200 irregulars. According to Henry Laurens (scholar), the Palestinians suffered double the Jewish losses, with 13,000 dead, 1,953 of whom are known to have died in combat situations. Of the remainder, 4,004 remain nameless but the place, tally and date of their death is known, and a further 7,043, for whom only the place of death is known, not their identities nor the date of their death. According to Laurens, the largest part of Palestinian casualties consisted of non-combatants and corresponds to the successful operations of the Israelis.. How many more Palestinians than Egyptians died?
