As part of the wide-ranging operation to secure Egypt"s borders, 158 "criminal elements" were arrested. The armed forces also neutralised 385 explosive devices that insurgents planted targeting security forces. The army did not specify when the deaths and arrests took place, saying only that they happened as part of "recent efforts" against extremists. The Sinai Peninsula, in the north-east of the country, is the epicentre of a hardened extremist insurgency spearheaded by Daesh. In February 2018, the army launched a nationwide operation against militants, focusing mainly on the North Sinai region. Some 650 militants and around 45 soldiers have been killed since the start of the offensive, according to the armed forces. No independent statistic are available to verify the deaths and the region is largely cut off to journalists. Terror attacks have surged following the 2013 military ouster of president Mohamed Morsi, who was replaced by former army general Abdel Fattah al-Sisi. The Egyptian president has presented himself as a bulwark against terrorism and a rock of political stability amid a region in turmoil.
