Saudi official: Kingdom 'warned the United States IN WRITING about Boston Bomber Tamerlan Tsarnaev in 2012

The Kingdom of Saudi Arabia sent a written warning about accused Boston Marathon bomber Tamerlan Tsarnaev to the U.S. Department of Homeland Security in 2012, long before pressure-cooker blasts killed three and injured hundreds, according to a senior Saudi government official with direct knowledge of the document.

As many as 4 million Muslims make pilgrimages annually to the Grand mosque in the city of Mecca. Tsarnaev sought to join them for an 'Umrah' journey, a trip that happens outside of the month reserved for the annual Hajj

The Saudi warning, the official told MailOnline, was separate from the multiple red flags raised by Russian intelligence in 2011, and was based on human intelligence developed independently in Yemen.

Citing security concerns, the Saudi government also denied an entry visa to the elder Tsarnaev brother in December 2011, when he hoped to make a pilgrimage to Mecca, the source said. Tsarnaev's plans to visit Saudi Arabia have not been previously disclosed.

I can assure you that the last has still not been heard of these brothers. We shall see

Boston bombing suspect moved to prison from hospital

 Dzhokhar Tsarnaev

Boston bombing suspect Dzhokhar Tsarnaev has been moved from a hospital to a prison medical center in Massachusetts, a US marshal’s spokesman told CNN Friday.
Tsarnaev was sent to the Federal Medical Center Devens, spokesman Drew Wade said.
The facility is about 40 miles (65 kilometers) northwest of the Boston-area hospital where Tsarnaev has been convalescing since he was found critically wounded in a boat in a massive police manhunt, days after the bombing which killed three and wounded 264.
The 19-year-old ethnic Chechen has been charged with using a weapon of mass destruction and could face the death penalty if convicted in US federal court.
His older brother, Tamarlan Tsarnaev 26, also accused of participating in the twin bombing, was killed in an explosive shootout as the two tried to evade police in a stolen car.

Boston bombing manhunt: Second bomber apprehended

Dzhokar Tsarnev, main image after his capture and top right, the man believed to be the terrorist behind the Boston bombings is in custody after he was cornered in a boat in a Boston backyard and appears to be wounded but still alive. The owner of the boat David Henneberry reportedly emerged from his house after the curfew in Boston was lifted, saw blood on the vessel, lifted the cover and discovered a person inside. He then fled back to his house and called police, according to CNN. Flash-bangs were being thrown in by police who had surrounded the area to try to flush out the suspect who appeared to have been at the location for most of the day

More on the Boston Marathon bombers

UPDATED Scores of heavily-armed police swarmed a Boston suburb this morning as the net tightened around an 'armed and dangerous' teenager suspected of being one of the two Boston bombers. During a dramatic night that paralysed the city, the two suspects killed an MIT police officer and hurled explosives at police in a car chase and gun battle that left one of them dead and his brother on the loose. The FBI's 'Suspect 1' was today revealed to be Tamerlan Tsarnaev, 26, (pictured left) who was killed in last night's firefight while 'Suspect 2' was named as his 19-year-old brother Dzokhar (pictured right) who is on the run and said to be 'armed and dangerous' with a bomb strapped to his chest.

Picture: Boston marathon killer walking away calmly

A new image has emerged of the second suspect in the Boston Marathon bombings calmly walking away from the scene of carnage. The image taken by Florida businessman David Green emerged just hours after the FBI lodged an appeal to identify two suspects behind the attacks that killed three and injured over 180. His picture shows runners and spectators fleeing in panic around the suspect, closely resembling the man identified by officials as Suspect Number Two, who is wearing a white basketball cap and a dark hooded sweatshirt. Mr Green has spoken to the FBI and told the New York Times and CNN's Piers Morgan that agents believe the man is Suspect Number Two.

One of the Boston bombing suspects is dead and the second is on the loose and said to be 'armed and dangerous' after a dramatic shootout in the suburbs of the city.

The terrorist dubbed 'Suspect 1' by the FBI died in hospital with multiple gunshot wounds and possible blast injuries after a fierce gun battle rocked the Watertown area hours after a police officer was shot dead at the nearby MIT campus.

The other, named today as 19-year-old Dzhokhar A. Tsarnaev, of Cambridge, Massachusetts, who was seen on CCTV wearing a white baseball cap, has gone on the run.

Boston Police Chief Ed Davis said: 'There is a terrorist on the loose who wants to kill people - do not open your door'.

Today, sources said the suspects were believed to be brothers from the Russia region near Chechnya and had lived in U.S. for at least one year.

Boston was in lockdown as police hunted the second suspect through the streets, with all mass transit shut and residents warned to stay inside.

A transit police officer was critically wounded in the exchange of gunfire with the suspects, police added.
