Analysis of information sources in references of the Wikipedia article "List of Irgun attacks" in English language version.
Attackers described by police as Jewish extremists today ambushed a police dawn patrol, which daily combs railway lines for bombs, blasting its ramshackled hand-propelled trolly and killing all six officers aboard. The "suicide patrol," which was instituted two weeks ago when Irgun Zvai Leumi said it was launching an anti-railway drive was ambushed at Beit Safafa on the outskirts of Jerusalem. The patrol had been appearing daily at the same spot, a few minutes after starting its track inspection tour of the Jerusalem yards. Killed were two British constables, one arab sergeant and three arab police officers. Another train attack near Jaffa left a fireman and an Arab police guard wounded and stranded the day's first passenger train. In both attacks police said explosives buried between crossties were electrically detonated. The Palestine Railway Administration announced suspension of all passenger train service on the Jerusalem-Lydda and the Lydda-Jaffa line until further notice. A statement signed "Irgun Zvai Leumi," which said that Jewish underground organization took full responsibility for recent attacks on railways, were pasted on numerous walls in Jerusalem last night. Railway schedules have been restricted to daytime runs only since attackers against trains reached their height. Today's attackers raised to 14 the number of blasts at railways in the past month. Damage to tracks today at both places was negligible and traffic was scheduled to be resumed during the day. Police sources expressed apprehension about reaction to today's attacks, commenting that it was "Jewish terrorism but it left four Arabs dead and one wounded and both attacks occurred in Arab territory."
