LONDON -- A man was killed by knife-wielding assailants on a London street Wednesday, and a bloodstained suspect at the scene holding a meat cleaver was captured on video telling passers-by: "We swear by the almighty Allah."

Eyewitnesses said the two attackers were later shot by officers, and described the victim as being chopped like a "piece of meat." Those two men were taken to a hospital where they were later arrested. Read full story

Soldiers carry coffins during the funeral of dozens of soldiers killed in Monday's suicide bombing in Sanaa on May 24. A man with explosives strapped under his army uniform killed more than 90 people in the Yemeni capital Sanaa on Monday when he blew himself up in the midst of a military parade rehearsal, the defence ministry said.

Funerals were held today for the victims of Monday's suicide bombing in Sanaa, Yemen. The attacks killed more than 90 people at a military parade rehearsal and wounded about 200 others. On Tuesday, the National Day parade was relocated to air force academy under heavy security. Reuters reports:

Yemeni soldiers marched in a National Day parade on Tuesday as the president watched from behind a bullet-proof glass shield in a show of defiance after a bomber killed more than 90 troops in an attack on the ceremony's rehearsal.

A somber mood hung over the event, meant to celebrate the 1990 unification of north and south Yemen, but it passed off without any repeat of Monday's bloodshed despite militant threats to carry out more attacks.

The bombing, one of the deadliest in Yemen in recent years, was a setback in its battle against Islamists linked to al Qaeda and heightened U.S. concerns over a country in the front line of Washington's global war on militants. Continue reading.

Twelve-year-old Tarana Akbari after visiting her sister who was wounded in a bomb attack against Shiite Muslims, in a hospital in Kabul on Dec, 8. Akbari was photographed crying surrounded by injured and dead relatives after surviving a bomb blast on Dec. 6 near a shrine on the Shiite holy day of Ashura. Afghanistan said the death toll from bombings targeting the Shiite Muslim holy day of Ashura, which raised fears the nation could face an eruption of sectarian violence, has climbed to 80. The twin blasts have prompted fears that Afghanistan could see the sort of sectarian violence that has pitched Shiite against Sunni Muslims in Iraq and Pakistan.

Twelve-year-old Tarana Akbari kisses her grandfather's hand as she walks on the yard with the help of her uncle (right) outside her home in Kabul on Dec. 10.

By now, you may have already seen the photo of Tarana Akbari reacting as she is surrounded by the bodies of her relatives, victims of a suicide bombing on a Shiite Muslim shrine in Kabul, Afghanistan on Dec. 6. The photo of the 12-year-old girl in her bright green dress, covered in blood became the defining image of the day's attacks, which resulted in the deaths of over 70 people, both young and old. It appeared the next day on the front pages of The New York Times, The Washington Post and The Wall Street Journal.

We now know her story. Akbari spoke about her experience to Agence France Presse, recounting the horror and fear she felt last Tuesday. That morning, she especially chose her custom-made, bright green dress for the occasion of Ashura; green is a holy color in Islam. She says:

Suddenly there was an explosion. It was as if the world had overturned, as if all the walls had collapsed on me. Little by little, I started to recognize my relatives. I screamed and I was watching as they died.

Akbari lost seven relatives in the attacks, including her 7 year-old brother, and her two sisters are still in the hospital. She was also injured, according to the Telegraph, and spent three days in the hospital due to shrapnel wounds. When she went to visit her family's grave, she was walking with a limp.

The photographer, Massoud Hossaini, who took the picture of Akbari on Dec. 6, was also interviewed by AFP. When the bomb went off, he instinctively ran in the opposite direction of the fleeing people and ended up in the same spot where the suicide bomber had been, surrounded by dead bodies. Although in a state of shock, he knew he was witnessing something that needed to be documented:

I was hoping just to reflect the real pain to everybody else, to everybody who is watching my photos. Doesn't matter [if] they are Afghans, they are American, they are Muslim, they are Christian, they are whatever. Just wanted that they know what my people are feeling now.

While still haunted by the visions of that day, he felt some solace knowing his image was widely published and helped bring attention to the suffering in Afghanistan.

New York Times front page on Wednesday, Dec. 7., 2011.

There were many gruesome images of the death and devastation from yesterday's suicide bombing on a Shiite Muslim shrine in Kabul, Afghanistan. In our PhotoBlog post on the attack, we made the decision not to publish some of the more gory pictures that depicted dead bodies and people with severed limbs.

The New York Times published one of these pictures today at 4-columns on the front page of their paper. We saw this powerful image yesterday, and chose not to publish it at the time because we thought the dead bodies of children would be too disturbing to our readers. The photographer, Massoud Houssaini, was on the scene when the attack took place and was able to make strong images of people immediately reacting to the devastation. According to Houssaini's Twitter account, he sustained a "small injury on his left hand but its ok now." The image is now included in this post, below the graphic warning.

What are your thoughts about the picture? Should we have published it yesterday?

The AP reports from Baghdad:

Iraqi officials say a late night rocket attack on Baghdad's heavily fortified Green Zone has killed four Iraqis and wounded 10.

A police officer says militants fired a Katyusha rocket late Monday night as Americans were celebrating Fourth of July at the U.S. Embassy, located in the Green Zone. The officer says the rocket hit a residential complex for laborers working at a hotel and sparked a fire.

A doctor at a nearby hospital confirmed the casualties.

Both spoke on condition of anonymity because they were not authorized to release information.

The sprawling Green Zone houses Iraqi government headquarters and the U.S. and British embassies. It's a favorite target for insurgents' mortar and Katyusha attacks.
