CAIRO - An Egyptian police officer was shot dead in a Nile Delta town on Thursday while trying to arrest suspects wanted in connection with a killing of a security official, the interior ministry said.
Captain Ahmed Samir came under fire during an early morning operation to arrest militants in the province of Qulubiya, the ministry said in a statement. They were suspected of involvement in the shooting in Cairo on Sunday of Interior Ministry Lieutenant Colonel Mohamed Mabruk.
Mabruk's killing deepened concerns that Egypt, a US ally, could face an Islamist insurgency.
He was part of an Interior Ministry unit that closely tracks the Muslim Brotherhood, which won every election since a popular uprising toppled autocrat Hosni Mubarak in 2011.
One of the Brotherhood's leaders, Mohamed Mursi, was ousted as Egypt's president by the army in July. Since then, attacks by Islamists based in the Sinai Peninsula near Israel have risen sharply.
