Pakistan's nuclear facilities have already been attacked at least thrice by its home-grown extremists and terrorists in little reported incidents over the last two years, even as the world remains divided over the safety and security of the nuclear weapons in the troubled country, according to western analysts.

The incidents, tracked by Shaun Gregory, a professor at Bradford University in UK, include an attack on the nuclear missile storage facility at Sargodha on November 1, 2007, an attack on Pakistan's nuclear airbase at Kamra by a suicide bomber on December 10, 2007, and perhaps most significantly the August 20, 2008 attack when Pakistani Taliban suicide bombers blew up several entry points to one of the armament complexes at the Wah cantonment, considered one of Pakistan's main nuclear weapons assembly.

This is certainly an under reported story in the USA and a very, very scary scenario. It is one of the nightmares facing the USA, the West, Israel, India and others. 

According to the Wall Street Journal:

A low-flying commercial airplane escorted by military jets Monday morning sent workers worried about a repeat of the Sept. 11, 2001, terrorist attacks fleeing their offices in the New York City area.

At around 10 a.m. EDT, a Boeing 747 was seen flying low over the southern tip of Manhattan and at one point was seen circling the Goldman Sachs Tower in nearby Jersey City, N.J.

The U.S. Defense Department was conducting a "photo op" that involved deploying two F-16 fighter jets escorting the 747 in the vicinity of Lower Manhattan and the Statue of Liberty, said Federal Aviation Administration spokesman Jim Peters.

The Port Authority of New York and New Jersey, which operates bridges, tunnels and airports in the area, said they had no knowledge of the low-flying plane.

All I can say is: Are you kidding me? What were they thinking? Try informing the public in advance.
