Original sentence: Egypt denied planning to attack Israel and called the air strikes an act of aggression.Initially Israel told the UN that Egypt had struck first but it subsequently withdrew this claim and said it had taken preemptive action because it believed an Egyptian attack was imminent.On June 5, 1967, Israel launched a bombing raid on Egyptian airfields.The issue of whether or not Israel's action was genuinely preemptive remains disputed
Edited sentence: On June 5, 1967, Israel launched a preemptive attack on Egypt.The Arab countries denied planning to attack Israel, and asserted that Israel's strike was not preemptive but an unwarranted and illegal act of aggression
