CAIRO - An Egyptian policeman and a militant were killed when security forces raided a hideout used by radical Islamists near Alexandria on Wednesday, and a senior officer was killed near Cairo when a bomb blew up his car, the Interior Ministry said.
Militant violence has spiraled since last July, when the army toppled elected head of state Mohamed Mursi and the authorities launched a fierce crackdown on his supporters in the Muslim Brotherhood and other Islamist sympathizers.
The attacks underline lingering instability in Egypt ahead of a presidential election in May that Abdel Fattah al-Sisi, the former army chief who deposed Mursi, is expected to win. The prime minister said the state was in "a fierce war" on terror.
The hideout targeted by police at dawn on Wednesday was used by Ansar Bayt al-Maqdis, or Supporters of Jerusalem, the group behind some of the deadliest attacks of the last nine months, the Interior Ministry said.
The militants had opened fire on the security forces as they arrived at the hideout in Borg El Arab, some 45 km (28 miles) south-west of Alexandria.
The police officer killed in the raid was named as First Lieutenant Ahmed Saad and the dead militant as Hassan Abdel Aal, a 25-year old from the Nile Delta province of Dakahlia.
Two other militants were detained, the ministry spokesman, Hany Abdel Latif, said in a televised statement. Footage broadcast on state TV appeared to show the body of a militant on the ground.
The militants were "among the dangerous elements of the terrorist group Ansar Bayt al-Maqdis, which was planning to target police and military facilities and the security forces", the ministry said.
The police seized weapons including explosive belts, automatic weapons, hand grenades and ammunition.Around 500 people have been killed in attacks since last July, mostly policemen and soldiers. The threat has been compounded by a flow of weapons from neighbouring Libya.
"The state ... is in a fierce war against the forces of terror and extremism that want to obstruct the country's path," Prime Minister Ibrahim Mahlab said in comments posed on an official Facebook page on Wednesday.
The police officer killed near Cairo on Wednesday was named as Brigadier General Ahmed Zaki. State
media said he was killed outside his home in 6th of October City, 32 km (20 miles) outside Cairo, when a bomb placed under his car went off.
Two conscript policemen were wounded in the bombing.
Ansar Bayt al-Maqdis has claimed responsibility for attacks including a failed attempt to blow up the interior minister last September, and large bomb attacks on police stations.
The United States this month designated Ansar Bayt al-Maqdis as a terrorist group. The group first emerged in the Sinai Peninsula in 2011 after the downfall of Hosni Mubarak. Since last summer, it has switched its focus from attacking Israel to targeting Egyptian security forces.
It has also claimed responsibility for a Feb. 16 attack that killed three South Korean tourists in the Sinai Peninsula.
The army-backed authorities have declared the Muslim Brotherhood a terrorist group and accuse it of a role in violence. The group says it is committed to peaceful activism.
