Syria's oil, gas and mineral resource industries have suffered losses totaling more than $50 billion since the country's conflict erupted in 2011, the oil minister said in comments published Tuesday, according to AFP.

Oil Minister Suleiman al-Abbas was quoted as saying by Syria's Al-Watan newspaper that attacks carried out by "terrorist" groups and US-led air strikes on jihadists have severely damaged infrastructure.

The figure is more than double the government's last announcement in June 2014, when it said Syria's oil and gas industries had lost $21.4 billion.
