A Saudi criminal court sentenced a Yemeni man to death Sunday for a knife attack on a Spanish theatre group performing in Riyadh last month, state television said.
The court also sentenced an accomplice to 12 years and six months in jail for the November 11 attack which Riyadh has linked to militant group Al-Qaeda, and which Madrid said left four performers wounded.
"The criminal court issues a preliminary ruling handing the death sentence to the perpetrator of the terrorist attack... in Riyadh," the official Al-Ekhbariya television reported.
The assailant, identified by Saudi police as a 33-year-old Yemeni, went on a stabbing spree during a live musical in the capital's King Abdullah Park, one of the venues hosting the two-month "Riyadh Season" entertainment festival.
Last week, Al-Ekhbariya said the attacker took orders from an Al-Qaeda leader in Yemen, but so far there has been no claim of responsibility from the group.
Al-Ekhbariya did not offer any details on his alleged accomplice.
Saudi Arabia is leading a military coalition supporting the Yemeni government against the Iran-backed Huthi rebels and has also been involved in the fight against Al-Qaeda.
Al-Qaeda in the Arabian Peninsula (AQAP), which is active in Yemen, is considered by the United States as the radical group's most dangerous branch.
Observers also point at burbling resentment among arch-conservatives in the kingdom over the multi-billion dollar entertainment push.
The Riyadh Season festival is part of a broad government push to open up the kingdom to tourists and diversify its economy away from oil.
The Saudi Crown Prince Mohammed bin Salman has pursued sweeping social reforms that mark the biggest cultural shakeup in the kingdom's modern history, allowing mixed-gender concerts and the reopening of cinemas.
Although the reforms are wildly popular among Saudi Arabia's mainly young population, they risk angering religious hardliners in the deeply conservative nation.
