Two Palestinian scientists were found dead in an apartment in Algeria, reports in Gaza said on Sunday. The circumstances surrounding their deaths were unclear.

The two, identified as Suliman al-Farra, 34, and Mohammed Albana, a 35-year-old physician, from Khan Younis in the Gaza Strip. The report said that they were found dead in al-Farra's apartment, in Zeralda, a suburb of the capital Algiers.

According to the reports, the Palestinian Embassy in Algeria told the family of one of the deceased that the two died of gas inhalation or due to a short circuit. Some Palestinian reports claim they were assassinated, however, there was no official confirmation.

Albana's brother said on Sunday, "We don’t have any more details, I expect the authorities in Algeria and the Palestinian embassy there to do everything necessary to understand what happened."

According to his brother, both families were trying to locate the men and called on Palestinians in Algeria for help. They broke into the apartment where both men were found dead.

Palestinian scientists and experts around the world have been killed in recent years in assassinations alleged to be carried out by Israel's Mossad espionage agency.
