President Abdel Fattah al-Sisi also ordered a curfew in the areas near Egypt's borders with Israel and the Gaza Strip.

Attacks on security men and premises have been growing since the ouster of former Islamist president Mohamed Morsi by the military in July 2013 and the massive security crackdown on his supporters, which left about 1,000 of them dead while thousands more were arrested.

Sinai blast toll in Egypt reaches 30

The soldiers' death toll has risen to 30 in the car bomb blast that targeted a security checkpoint in Egypt's North Sinai province on Friday, with 28 injured, a security source said.

"The blast targeted the military checkpoint of Karm al-Qawadis in Sheikh Zuweid, as a suicide bomber drove a car with more than five tonnes of explosives into the checkpoint," the source said, suspecting that the attacker belongs to the Sinai-based Al Qaeda- inspired group Ansar Bayt al-Maqdis, or Champions of Jerusalem, that has claimed responsibility for several previous attacks, a local media reported.

President Abdel-Fattah al-Sisi has ordered the national defence council to convene for an emergency meeting to discuss the situation in Sinai.

Sisi presided the meeting that was participated by the prime minister, the ministers of defence, interior and finance, as well as the military chief of staff and other senior officials, state media reported.

There was no immediate claim of responsibility for the attack.
