However instants later on they pull out rifles as well as get rid of 3 Palestinians. Within ten moments they are gone. Israel says it did away with 3 revolutionaries throughout the bust on January 30th and fended off a major strike which loomed.

However disguising combatants as clinical personnel possibly breaks global law, which forbids “perfidy”. What is that criminal activity?
