A military court in the Hamas-run Gaza Strip on Monday sentenced six people, including a woman, to death for "collaborating" with Israel, authorities said.
In total 14 people were sentenced for "collaborating with the occupation," with five sentenced to be hanged and one shot, the interior ministry in Gaza said.
Eight others were sentenced to hard labour ranging from six to 15 years.
The rulings came after eight people were killed when an Israeli special forces operation in Gaza was uncovered on November 11, leading to a vicious firefight.
Hamas fired hundreds of rockets at Israel in response, with the Jewish state striking dozens of targets in Gaza before a November 13 ceasefire agreement.
The six sentenced to death Monday were not directly related to the flareup, officials said.
Iyad al-Bozum, the spokesman of the interior ministry in Gaza, told AFP they were linked "to a communications and eavesdropping device planted by the (Israeli) occupation". 
Six Hamas members were killed when the device apparently exploded after detection near Deir al-Balah in central Gaza in May.
The six condemned to death on Monday ranged in age from 29 to 55 and had each allegedly been working with Israeli intelligence for several years.
Among those sentenced to hang was a woman living inside Israel, named as Amal Mahmoud, 55.
She was sentenced in absentia and is alleged to have encouraged her nephew in Gaza to collaborate with Israeli intelligence, according to the interior ministry.
Bozum hailed the rulings as a "clear message" to those who would cooperate with Israel.
"Collaborators must realise the (Israeli) occupation will not be able to protect them," he told a news conference.
