A witness said on Twitter that 'nowhere feels safe' after the string of violence this week in London.

It is the second act of violence to rock London in 48 hours after terrorist Usman Khan stabbed five people, killing two, on London Bridge on Friday.

Borough Market was also targeted by terrorists in the London Bridge attacks of 2017.

In recent years London has seen a surge of acid attacks. In January two men were rushed to hospital after being splashed with acid near Kings Cross.
