Cairo: At least 35 Egyptian troops and police officers have been killed in clashes with Islamist fighters in the Bahariya oasis in the country's Western Desert, security and medical sources said.
An interior ministry statement confirmed the yesterday's incident and said some of the "terrorist" attackers had died, without giving any figures for casualties or further details.
The small extremist group Hasm claimed the attack, saying in a statement that 28 members of the security forces were killed, with 32 injured.
Since the army removed President Mohamed Morsi, of the Muslim Brotherhood, extremist groups have increased their attacks on the country's military and police.
Authorities have been fighting the Egyptian branch of the jihadist group Islamic State, which has increased its attacks in the north of the Sinai peninsula.
Hundreds of soldiers and police have been killed in the attacks.
Hasm has claimed multiple attacks since 2016 on police, officials and judges in Cairo.
In their statements, the groups do not claim any affiliation to the Muslim Brotherhood.
The Islamic State group's deadly attacks on the military and police include a recent assault on a checkpoint in Sinai on July 7 that killed at least 21 soldiers.
The group has maintained a steady war of attrition with sniper attacks and roadside bombings.
But unlike their parent organisation in Iraq and Syria, they have been unable to seize population centres in the peninsula bordering Israel and Gaza.
In October 2015, IS claimed the bombing of a Russian airliner carrying holidaymakers from the popular South Sinai resort of Sharm el-Sheikh, killing all 224 people on board. (AFP)
