London: The security agencies of the United Kingdom were keeping a tab on the man known as jihadi John and who is suspected to be the killer of two American journalists James Foley and Steven Sotloff, before he went to the Middle East.
As per reports in a foreign daily, the man was known to MI5 as a low-level collector for genuine Arab charities which based in London.
Later he allegedly graduated to gathering funds for the terror group ISIS or the Islamic State. And from thereon he decided to fight for the ISIS.
Initially he was considered as a low-level risk by the security agencies as he was only into street collection and is considered to have been radicalised overnight, as per the report.
Various reports have said that there is no confirmation as to whether the voice in the videos released on the internet actually belongs to the the black-clad figure who killed the two US citizens.
It is also said that some part of the video may not be genuine.
John is one of a group of four British IS fighters dubbed as 'The Beatles'.
Meanwhile, British PM David Cameron is all for forging an international alliance against the ISIS.
In the recent times the US has also upped the ante against the terror group with air strikes by its war planes. The air strikes began in early August after ISIS fighters began targeting ethnic Yazidis and launching attacks toward the Kurdish regional capital of Irbil.
Th Iraqi and Kurdish forces have also launched offensive against the ISIS in a major way.
US president Barack Obama vowed to destroy the ISIS after it beheaded a second American citizen and put up the video on the internet.
Sotloff was killed by the group last Tuesday.
In the video, the ISIS had blamed Obama's decision to conduct air strikes against the militant group in Iraq for the execution.
The video of Foley's execution was released last month.
