Majority of my family lives in London, have done so since I was a kid. I can still remember the days that Grandma used to write us letters and I would wonder why her pen slipped off the page... This was because bombs were going off, thanks to the IRA.
As my uncle says, try in these times to stay away from Public transport, catch cabs or stay inside.
Be careful people! Hopefully the government can assert some dominance, flush these guys out. Terrorists we do not fear you!
Well said.
