This action led the British Parliament to discuss the disturbances in Palestine. On 23 February 1939 the Secretary of State for the Colonies, Malcolm MacDonald revealed the British intention to cancel the mandate and establish a state that would preserve Arab rights. This caused a wave of riots and attacks by Arabs against Jews. The Irgun responded four days later with a series of attacks on Arab buses and other sites. The British used military force against the Arab rioters and in the latter stages of the revolt by the Arab community in Palestine, it deteriorated into a series of internal gang wars.
