A terrorist group in the Sinai Peninsula fired three rockets at an Egyptian military base Sunday near the northern Sinai town of Sheikh Zuweid. No injuries were reported, Israel Radio reported.

Ansar Bayt al-Maqdis, an al-Qaeda affiliated terrorist organization, reportedly claimed credit for the attack.

The Sinai-based al-Qaeda-linked group was also responsible for firing two rockets at Eilat Friday. One of the rockets was intercepted by the Iron Dome missile defense battery, and no injuries or damage was reported.

The group said in a statement that the Friday’s rocket attack was prompted by “the cooperation between Egypt and Israel and the bombing of Gaza residents.” Israel launched airstrikes against targets in the Gaza Strip early Friday morning in retaliation for a rocket fired at the southern city of Netivot.

Ansar Bayt al-Maqdis (Partisans of Jerusalem) has also claimed responsibility for several high-profile attacks in Egypt, including a car bombing at police headquarters in Cairo, shooting down a military helicopter with a missile and assassinating a police general in broad daylight in the capital.

The Egyptian military has been consistently fighting against militant forces in the Sinai since a military-backed coup toppled former president Mohamed Morsi’s government in July. The army has poured troops into the Sinai in a bid to crush the militants but despite the loss of scores of police and troops, there has been no let-up in attacks.
