Even as you read this, constant updates are coming through about the blast in New York, in which about 30 people are said to have been injured. Reports state that some devices have been found in the vicinity, with a pressure cooker with an attached wire and cell phone. Readers will recall that pressure cooker bombs were used during the Boston Marathon in 2013, when three people died and many were injured.

Before the explosion in Chelsea, reports flooded in about a pipe bomb explosion in New Jersey. There too, other devices were being looked at and the discovery resulted in cancellation of a charity 5K race for US Marines and their families. There were no injuries in New Jersey. Even as you read this, there is constant change in the reports and shifting stances by politicians.
