A special tribunal dealing with anti-terrorism cases handed down the punishment for carrying out a terrorist attack using firearms, murder and financing terrorism, prosecutor Abdullah Abu said.

One person was acquitted, he added.

The army killed five militants and one associate in its operation to free hostages.
