Swedish journalist Nils Horner was fatally shot Tuesday in what is regarded as a generally secure area of the Afghan capital, Swedish Radio said.

Horner, 51, was interviewing people in the street when two unknown persons came up behind him and shot him in the back of the neck, Swedish Radio's director-general, Cilla Benko, told a press conference in Stockholm.

The incident occurred in a protected area where diplomatic legations are located.

Swedish Radio news chief Anne Lagercrantz said that hours before the incident she had spoken with Horner, and when the news broke that a foreigner had been killed in Kabul, the editorial department tried to contact him again.

When Horner's telephone rang, another man answered who identified himself as an emegency-room doctor and said that the reporter was dead, Lagercrantz recounted.

The reporter, a Swedish-British dual national who had previously worked in London and New York, had served since 2001 as a correspondent for Swedish Radio, chiefly in Asia.

For that station he covered the fall of the Taliban regime, the entry of U.S. troops into Baghdad, the 2004 Asian tsunami and the Fukushima nuclear disaster in Japan.

"Nils was one of our absolute best and most experienced correspondents and what has happened to him today is terrible. We are now trying to get as many details as we can," Benko said in a statement. EFE
