A new issue of the al Qaeda-published propaganda magazine Inspire crows about recent terrorist attacks in Boston and the U.K. and urges young Muslims to carry out similar “lone wolf” operations against the West.

An English-language version of the spring 2013 issue of the online publication, obtained Thursday by NBC News, contains multiple articles praising alleged Boston Marathon bombers Tamerlan and Dzhokhar Tsarnaev and one on last week’s gruesome knife slaying of a British soldier in London.

“When one looks at the terrific Boston Marathon operation and its aftermath, including the accusation of the two brothers, Tamerlan and Dzhokhar Tsarnaev, he understands how a single lone jihad operation can force America to stand on one foot and live in a terrified state, full of fear and rare restlessness,” reads one article under the byline Abu Abdillah Almoravid.

Unlike the last edition of the publication in March, which contained bomb-building recipes – including one using a pressure cooker, similar to the devices deployed near the marathon finish line – and other suggested methods for inflicting small-scale terrorism, the new 39-page issue has numerous pieces aimed at the American audience.

A “Letter from the Editor” warns, “Americans, you should understand this simple equation: as you kill you will be killed. The war is yet to cease, it has barely started. Yesterday it was Baghdad, today it is Boston. The question of ‘who and why’ should be kept aside, You should be asking, “Where is next?”

“Leave us with our religion, land and nations and mind your own internal affairs,” warns another titled “Message to the American Nation” and supposedly written by al Qaeda in the Arabian Peninsula Commander Qassim Ar-Relmy. “Save your economy, look after your concerns.”

The articles also contain numerous high-resolution photos showing the carnage at the Boston Marathon finish line after the bombing on April 15 and one showing the blood-covered suspect in the London slaying of British soldier Lee Rigby.

The gleeful tone extends to the tornado that struck Moore, Okla., on May 20, with an article on that disaster saying, “The Oklahoma tornado took lives, destroyed properties, and still nations, Muslims and others alike, celebrated and prayed for more to strike America. They love to see America in calamities!”

Evan Kohlmann, a partner in the security firm Flashpoint Partners and a terrorism analyst for NBC News, said the leak of the new issue of Inspire follows several weeks of cyberattacks against al Qaeda's online media network by unknown hostile parties, one of whom apparently managed to penetrate the group's network and briefly post a fake issue.

Last week, U.S. Attorney General Eric Holder identified the previous editor of the propaganda organ, Samir Khan, as one of four Americans killed by U.S. drone strikes overseas.
