jazakallahu khair for your concern q8i and sr. Hawa, alhumdulillah, i am fine :)
I tend to get in for work at around 8am everyday so i was already in the office when the mayhem started.
I usually get off at Whitechapel and then walk 20 minutes to my office (so that i don't have to pay for a zone 1 travelcard) and on that route i walk past Aldgate & Aldgate East stations to the office.
Today i actually went in via Liverpool Street. So either way it could have been ka-blamow for me. But alhumdulillah, Allah spared me and my family from any grief, and we have nothing bad to report.
I did try to visit the scene during my lunch break but the police had cordoned off the area around Aldgate station and i couldn't get there.
It is a bad day for London, but i couldn't help but laugh when my brother told me that he was watching the afternoon news when the news presenter asked an expert "but could this have been the IRA?" and the expert replied, "oh no. This is too clever for the Irish." hahahaha
