In 1973, Carlos conducted a failed PFLP assassination attempt on Joseph Sieff, a Jewish businessman and vice president of the British Zionist Federation. On 30 December, Carlos called on Sieff's home on Queen's Grove in St John's Wood and ordered the maid to take him to Sieff. Finding Sieff in the bathroom, in his bath, Carlos fired one bullet at Sieff from his Tokarev 7.62mm pistol, which bounced off Sieff just between his nose and upper lip and knocked him unconscious; the gun then jammed and Carlos fled.
