A court in Egypt on Saturday ratified death sentences for 12 people convicted of planning attacks on behalf of the jihadist Islamic State (ISIS) group, AFP reported.
Six of those whose sentences were confirmed are in custody, while six were tried in absentia.
All were convicted of having joined ISIS, which has declared a "caliphate" in parts of Iraq and Syria under its control, and of plotting to attack Egypt's police force and military, according to AFP.
The court in the Nile Delta province of Sharqiya had recommended the death sentence for the men last month, and was awaiting the mufti's approval to ratify the ruling.
The mufti, the government's official interpreter of Islamic law, issues a non-binding opinion in such cases.
Those convicted can appeal a ruling before the Court of Cassation, which may either uphold the verdict or order a retrial.
Hundreds of Islamists have been sentenced to death since the military toppled Islamist president Mohammed Morsi in 2013.
Many, including Morsi himself, have appealed. Seven have been executed.
Morsi's overthrow unleashed a deadly crackdown on Islamists that killed hundreds of protesters.
In addition, Islamic State's Egypt affiliate, recently renamed Sinai Province, has killed hundreds of soldiers and police in the Sinai since Morsi’s removal and has claimed carried out a host of terrorist attacks in the region.
Among the attacks claimed by the group since Morsi's ouster was the assassination of a top Egyptian police general, who was gunned down as he left his home in a west Cairo neighborhood, and a bus bombing on a tour bus filled with South Korean tourists in the Sinai.
