The 1948 Anti-Jewish riots in Tripolitania were riots by the Arab against the Jewish communities of Tripoli and its surroundings in June 1948, during the British Military Administration in Libya. The events resulted in 14 Jews dead and destruction of 280 Jewish homes. The events occurred during the 1948 Arab-Israeli War.
 

The rioting began on June 12 in Tripoli, Libya.[5] This time, unlike the previous Tripoli pogrom, the Jewish community of Tripoli had prepared to defend itself. Jewish self-defense units fought back against the Muslim rioters.
 

According to the British reports, the rioting broke out spontaneously. The Jewish defense measures had been prepared beforehand, with the British noting signs in Hebrew stating "It is good to die for one's country", and stated that during the riots the role of the Jewish organization "was not purely defense" since "determined parties of young Jews battled with the police in efforts to break out of The Old City in order to attack Arabs". The rioting began with an argument between a Jew and an Arab in central Tripoli, in which other Jews and Arabs joined in. Within half an hour a crowd of Arabs had gathered and made their way towards the Jewish Quarter of Old City (also known as the "Jewish Hara"), armed themselves with sticks and stones, following which Jewish units threw bombs into the crowd. The rioting continued for the next hour, during which Jews on rooftops retaliated, and also attacked the police forces, throwing bombs, stones and small arms fire.
 

The riots resulted in the death of thirteen or fourteen Jews, four Arabs, with 38 Jews and 51 Arabs being injured, and causing extensive property damage, and leaving approximately 300 families destitute. Jews in the surrounding countryside and in Benghazi were subjected to additional attacks.
