The group said fighters struck an Israeli force of seven soldiers with a powerful explosive device near the Omar ibn Abd al-Aziz Mosque in the al-Tannour neighborhood in eastern Rafah.
The Brigades reported earlier that it targeted an Israeli engineering unit of 12 soldiers with two anti-personnel and anti-armor shells as the unit prepared to carry out a demolition operation inside a home near al-Fidai Junction in the same neighborhood.
The explosion inside the house caused multiple casualties, it said, and the group saw Israeli helicopters landing to evacuate the dead and wounded.
