Sick terror supporters used the attack, where at least one person has been killed and several injured, to urge for more atrocities on the West.
The string of texts were sent to 225 members of a WhatsApp group called ‘War news/Ummah news’ in the wake of the terror attack, where a van ploughed into Muslim worshippers in the early hours of this morning.
During the sick rant, ISIS sympathisers questioned why the attacker, who was armed with a knife, had not been shot by police like the London Bridge attackers.
The texts, reported by terrorism analyst Michael Smith, read: “Oh Muslimeen when your brothers took revenge on the crusader nationals for the slaughter they are carrying out on the Muslims, they were shot on site by the the British Police.
“Then how come the Police never shot a Kaafir [non-believer].
“Oh Muslims you need to wake up the war is starting now in your own streets outside your own Masajids.
“Your elders could be killed, your sisters could be attacked."
Home Secretary Amber Rudd confirmed the incident was being treated as a terrorist attack after at least one person was killed and at least 10 injured when the attacker struck at 1am.
Witnesses said the van struck pedestrians who were tending to an elderly man who had collapsed.
