Egypt's interior ministry said on Tuesday that police killed 11 terrorists in a shootout at a farm that was being used as a terrorist hideout in Ismailia governorate.
Police also confiscated equipment including three machine guns, one rifle, wireless communication devices, explosive materials, as well as large amounts of ammunition, the statement reads.
Several other hideouts were also raided by police forces, including in Ismailia and 10th of Ramadan City, which were used to stockpile equipment to be smuggled to North Sinai.
Police also arrested six people at one of the hideouts who were involved in providing support to terrorist groups in North Sinai, according to the statement.
Police forces also arrested three people who were part of a smuggling network that provided logistical support to terrorist groups in North Sinai.
Last week, gunmen in North Sinai murdered 305 worshippers – including 27 children – and injured 128 during Friday prayers at Al-Rawdah Mosque in Bir Al-Abd city.
No group has claimed responsibility for the terrorist attack; the deadliest in Egypt’s recent memory.
Shortly after the attack, President Abdel-Fattah El-Sisi promised vengeance in a televised speech to the nation.
El-Sisi said that the military and police “will avenge our martyrs” and will respond “using brute force” against the terrorists to ensure stability and security.
