US commandos zeroed in on Abu Bakr al-Baghdadi's final hideout with the help of an extraordinarily well-placed informant, an ISIS operative who facilitated the terrorist leader's movements around Syria and even helped oversee construction work on his Syrian safe house, according to US and Middle East-based officials knowledgeable about the operatio...

US spy agencies are seeing signs that North Korea is constructing new missiles at a factory that produced the country's first intercontinental ballistic missiles capable of reaching the United States, according to officials familiar with the intelligence.

A few months before his killing rampage, convicted robber and prison inmate Benjamin Herman had a jailhouse conversion of a sort. A white suburban teen and a nominal Catholic when he was first incarcerated, he emerged in late May as an avowed Islamist who would murder three people within hours of gaining freedom on a work-release program.

New details from a trove of Iranian nuclear documents stolen by Israeli spies early this year show that Tehran obtained explicit weapons-design information from a foreign source and was on the cusp of mastering key bomb making technologies when the research was ordered halted 15 years ago.

U.S. intelligence officials, citing newly obtained evidence, have concluded that North Korea does not intend to fully surrender its nuclear stockpile, and instead is considering ways to conceal the number of weapons it has and secret production facilities, according to U.S. officials.

His self-declared caliphate was in ruins when Abu Bakr al-Baghdadi summoned some of his top aides to a meeting in eastern Syria last year. The Islamic State's capital in Iraq had already fallen, and its Syrian headquarters was under siege.

Qatar had entered secret talks to free 25 of its citizens from Iraqi kidnappers, yet the bargaining had turned into a kind of group shakedown, the official said, with a half-dozen militias and foreign governments jostling to squeeze cash from the wealthy Persian Gulf state.

During his last run for the presidency in 2012, Russian leader Vladimir Putin startled U.S. military experts with a mysterious pledge to develop novel kinds of weapons to counter the West's technological edge.

The powerful intercontinental missile tested by North Korea late last year is "highly likely" to have been built with foreign blueprints or parts, according to a new technical analysis that describes multiple similarities between Pyongyang's new missile and ones built by the Soviet Union decades ago.

Precisely when the photo was taken is not known, but the message is chillingly clear. It has been repeated in similar posts in recent weeks, all purporting to show Islamic State operatives casing landmarks in Western cities and urging followers to carry out attacks wherever they are. "It is time to harvest the heads," the narrator in one such video...

A few months after the collapse of the Soviet Union, a group of American investors and Russian scientists struck a deal to begin marketing one of the crown jewels of Moscow's strategic arsenal: an entire family of missiles designed for launch from submarines.

Just before leaving his Defense Department job two months ago, intelligence officer Luis Elizondo quietly arranged to secure the release of three of the most unusual videos in the Pentagon's secret vaults: raw footage from encounters between fighter jets and "anomalous aerial vehicles" - military jargon for UFOs.

The woman's secret flight from the caliphate took place more than six months ago, aided by a smuggler who helped her sneak across the Syrian-Turkish border one spring night. But in spirit, this red-haired exile from the Islamic State never truly left.

The brazen attack on worshipers at an Egyptian mosque early Friday showed the ability of the Islamic State's regional affiliates to inflict death and exact revenge for the loss of the group's main enclaves in Iraq and Syria.

In Stockholm, the perpetrator was an Uzbek immigrant who careened down a busy shopping street in a hijacked beer truck, hitting 19 pedestrians before crashing his vehicle into a department store. Five of his victims died, including an 11-year-old girl.
