The army spokesperson said Saturday that the latest death count of the Sinai Friday attacks reached 30 army personnel.
A car bomb exploded in the Karam Al-Qawadees neighbourhood in Sheikh Zuweid, North Sinai, on Friday afternoon, killing at least 27 and injuring 20, state-owned Al-Ahram reported.
State media added that another attack took place in a checkpoint in Al-Arish, leaving three killed.
No group has claimed responsibility for the attacks so far.
The government declared a state of emergency in Sinai on Friday, with the closure of the Rafah border.
The Supreme Council of Armed Forces, headed by President Abdel Fattah Al-Sisi, is expected to meet on Saturday to discuss the latest acts of violence.
Over the past several months, confrontations between the military and “terrorist groups” have been frequent.
