The Argentine reporter who first broke the story about special prosecutor Alberto Nisman’s death, Damian Pachter, has fled to Israel fearing for his safety.

The journalist believed he was being followed by government agents.

In a tweet published on Sunday, Pachter announced he had arrived in Tel Aviv after an impromptu journey from Buenos Aires.

“Safe in Tel Aviv. Thank you to all. We will talk shortly,” Pachter wrote in Spanish.

In a column published on Haaretz, Pachter explains why he so quickly fled on Saturday. He believed he was being followed and took precautions to leave Argentina for Israel as he has citizenship in both countries.

After breaking the news of Nisman’s death, the Buenos Aires Herald reporter began suspecting something may be happening concerning him.

“On Friday I was working at the Buenos Aires Herald.com newsroom when a colleague from the BBC urged me to look at the state news agency’s story on Nisman’s death. The piece had some serious typos but the message was even stranger: The agency quoted a supposed tweet of mine that I never wrote,” he explained.

He then decided to take a bus that night and meet with a source; however, he realized he was being followed. At a gas station Pachter met his source, who confirmed he was being followed by an intelligence officer and snapped a photo of the alleged agent.

“I then had to consider the best thing to do, because when an Argentine intelligence agent is on your tail, it’s never good news,” Pachter wrote. He then decided to leave for Israel via Montevideo and Madrid.

While traveling to Tel Aviv, the government of President Cristina Fernandez de Kirchner published his plane ticket information on Twitter via the Casa Rosada’s official account. The Casa Rosada is Argentina’s presidential residence.

The tweet was accompanied with a message that said Pachter traveled to Uruguay and would return on Feb. 2.

The government continued to defend its decision to publish the ticket information on Monday when cabinet chief Jorge Capitanich explained that the ticket information had been made public by Pachter, citing the state-owned airline Aerolinias Argentinas, according to TN.com.

The state-run media outlet Telam first published the ticket information before the Casa Rosada tweet.

“It is said that a journalist feels threatened, his whereabouts are unknown, [and] his employer has was given no notification, so it is very important to publish the information to let the public know about his whereabouts,” Capitanich said in the press conference as the reason for the publishing of the ticket information.

If Pachter believed an intelligence officer was following him, he should publish the photo he took so the man can be identified, said Capitanich.

He then explained, “there is plenty of security for all journalists in Argentina.”

However, Pachter wrote in Haaretz that he met with his mother, friends and colleagues informing them of his destination and plans.

“Argentina has become a dark place led by a corrupt political system. I still haven’t figured out everything that has happened to me over the past 48 hours,” Pachter wrote. “I never imagined my return to Israel would be like this.”
