The New York Times quoted Iranian sources as saying that Tehran believes that Israel killed two Iranian scientists by poisoning their food last May.

The sources said that the two victims were Ayoub Taziri, an aviation engineer who worked at a military research center, and Kamran Aghmlai, a geologist.

One of the sources stated that symptoms of poisoning began to appear on my waiter after a dinner he attended in the city of Yazd (central Iran).

He pointed out that the invitation to the banquet disappeared after the incident, and that the Iranian authorities began searching for him.

According to the newspaper, waiting for me worked on projects related to missiles and aircraft engines at a government space center in the city of Yazd.

For his part, a representative of the Iranian Ministry of Justice denied the death of Tazeri as a result of the poisoning, and said that this was not accurate.

The Iranian official explained that waiting for me was not a prominent scientist, but an ordinary employee in a company, and he was sick and died of natural causes.

With regard to Aghlami, the newspaper referred to reports circulated by Israeli and Iranian media abroad, according to which he worked at the "Natanz" nuclear facility, but the victim's friends denied this, stressing that he was working in a private geological research company.

The New York Times quoted a friend of the geologist, Kamran Aghmalai, as saying that he developed severe symptoms of poisoning after returning to Tehran from a business trip to the city of Tabriz (northwest of Iran).

She stated that my wait and my children were transferred to intensive care in two hospitals in the cities of Yazd and Tehran, but their condition continued to deteriorate day after day until they died, noting that they were young and did not suffer from any health problems before their illness.

During the past decade, Iran witnessed a series of assassinations and attacks targeting a number of scientists and military personnel, in addition to nuclear facilities, and accused Israel of being behind them.

Last month, Hassan Sayyad Khodaei, a leader in the Quds Force of the Iranian Revolutionary Guards, was assassinated, and Tehran accused Tel Aviv of being behind his assassination, and vowed to respond.

death on the job

Two members of the Aerospace Forces of the Iranian Revolutionary Guards were killed in two separate accidents while on duty.

The Revolutionary Guards said - in a statement issued late on Sunday evening - that the officer in the Aerospace Forces, Ali Kamani, was killed in a traffic accident in the central city of Khomein while performing his duties, without giving further details.

Hours later, Fars News Agency - which is close to the Revolutionary Guards - reported the death of Muhammad Abdus, whom it described as an employee of the Aerospace Forces of the Revolutionary Guards, in the city of Semnan, east of the capital, Tehran, while performing his duties on Sunday.

The agency did not provide additional details about the circumstances of the death.

The Iranian Ministry of Defense later confirmed the death of Abdus, as the Public Relations Department said that he was an employee of the ministry.

She added that Iran's strengthening of its deterrence capabilities depends on the sacrifice and struggle of those who gave their lives for the benefit of the country, according to a statement by the Iranian Ministry of Defense.

Al-Jazeera correspondent in Tehran, Omar Hawash, said that the Aerospace Forces of the Revolutionary Guards includes Iranian fighter units, units responsible for manufacturing and launching missiles and satellite launch units, as well as unmanned aircraft.

He explained that talking about the tasks of the officers or employees of these forces may include testing new weapons and the accidents that occur during that, and it may also include administrative tasks.

The reporter pointed out that the elements of the Aerospace Forces of the Revolutionary Guards, especially the elite among them, are being targeted by the Israeli Mossad.

The spokesman for the Iranian armed forces, Brigadier General Abolfazl Shakarji, confirmed that Tehran would respond immediately to the slightest move against it.

On May 22, the Colonel of the Revolutionary Guards, Sayyad Khodaei, was shot dead by two people who were on a motorcycle while returning to his home in Tehran, and the finger was pointed at Israel.

On June 3, the Iranian News Agency quoted an informed source that a member of the Iranian Revolutionary Guard was killed in an accident inside his home, but at the same time he denied reports of the assassination of Colonel in the Revolutionary Guards, Ali Ismail Zadeh.

During 12 years, Iran lost a number of senior scholars, military and politicians in assassinations, accusing Israel of being behind their killing.
