New York Times correspondent Anthony Shadid, a two-time Pulitzer Prize winner who strove to capture untold stories in Middle East conflicts from Libya to Iraq, died Thursday in eastern Syria after slipping into the country to report on the uprising against its president.

Shadid, shot in the West Bank in 2002 and kidnapped for six days in Libya last year, apparently died of an asthma attack, the Times said. Times photographer Tyler Hicks was with him and carried his body to Turkey, the newspaper said.

"Anthony was one of our generation's finest reporters," Times Publisher Arthur Sulzberger said in a statement. "He was also an exceptionally kind and generous human being. He brought to his readers an up-close look at the globe's many war-torn regions, often at great personal risk. We were fortunate to have Anthony as a colleague, and we mourn his death."

Shadid's father, Buddy Shadid, told The Associated Press on Thursday his son had asthma all his life and had medication with him.

"(But) he was walking to the border because it was too dangerous to ride in the car," the father said. "He was walking behind some horses — he's more allergic to those than anything else — and he had an asthma attack."

The Times reported that Shadid and Hicks recently were helped by smugglers through the border area in Turkey adjoining Syria's Idlib Province and were met by guides on horseback.

Hicks told the newspaper that Shadid suffered one bout of asthma the first night, followed by a more severe attack a week later on the way out.

"I stood next to him and asked if he was OK, and then he collapsed," Hicks told the Times.

Hicks said that Shadid was unconscious and that his breathing was "very faint" and "very shallow." He said that after a few minutes he could see that Shadid "was no longer breathing."

Shadid, a 43-year-old American of Lebanese descent, had a wife, Nada Bakri, and a son and a daughter. He had worked previously for the AP, The Washington Post and The Boston Globe. He won Pulitzer Prizes for international reporting in 2004 and 2010 when he was with the Post.
