A car bombing killed an Egyptian woman and a child Friday in the North Sinai town of Rafah, where the military is engaged in a sweeping campaign against jihadists, the army said.

The military said that the bomb went off as troops combed the border town neighboring the Palestinian Gaza Strip, and there were no army casualties.

It launched an offensive against the Islamic State of Iraq and Syria group militants this week which it says has killed 134 jihadists since Monday.

At least two soldiers were killed during the operation, the army said.

The military says it has killed more than 1,000 militants since 2013, but the figures are difficult to independently verify.

The army is struggling to quell an ISIS insurgency in the Sinai Peninsula that has killed hundreds of soldiers and policemen since 2013, when the army ousted Islamist president Mohamed Mursi.
