The perpetrators confessed that they had set fire to several locations in the three governorates, and were first arrested last year, the Ministry of Justice statement said.
They were executed on Wednesday.
Eleven other people involved in setting the wildfires were given life sentences of hard labor, with four others sentenced to temporary hard labor, the statement said. Five minors were also given jail sentences ranging from 10 to 12 years for their involvement.
The fires affected 280 towns, damaged more than 370 homes and destroyed 11,000 hectares of forested land, with significant damage also caused to livestock, agricultural equipment and infrastructure, according to the Ministry of Justice. The fires spread across the provinces of Latakia, Tartous and Homs.
The Ministry of Justice statement said that the perpetrators admitted to planning to set the fires at the end of August 2020 and that they carried out the crimes “intermittently” from September until October 2020.
Capital punishment in Syria is permissible in the case of crimes including treason, espionage, murder and arson.
In 2017, Amnesty International shed a light on a campaign of mass hangings in Saydnaya Prison, located north of the capital Damascus.
The Ministry of Justice refuted the accusations.
