Militants kill 25 Egyptian policemen in Sinai

Islamic militants on Monday ambushed two mini-buses carrying off-duty policemen in the northern region of Egypt's Sinai Peninsula, killing 25 of them execution-style in a brazen daylight attack that deepens the turmoil roiling the country and underscores the volatility of the strategic region.

The killings, which took place near the border town of Rafah, came a day after 36 detainees were killed in clashes with security forces. In all, nearly 1,000 people have been killed in clashes between security forces and supporters of ousted president Mohammed Morsi since last Wednesday.

The military raided two protest camps of Morsi's supporters in Cairo on Wednesday, killing hundreds of people and triggering the current wave of violence.

Egyptian judiciary officials said Monday that former presidentHosni Mubarakcould be freed from custody this week.

They say a court ordered his release in a corruption case that alleged he and his two sons embezzled funds for presidential palaces.

Tensions in the countryhave been high since the army ousted Morsi in a July 3 coup, following days of protests by millions of Egyptians demanding the Islamist president leave and accusing him of abusing his powers.

But Morsi's supporters have fought back, staging demonstrations demanding that he be reinstated and denouncing the military coup.

Consular officials, meanwhile,have been in contact withtwo Canadians detained in Egypt.

John Greyson, a Toronto-based filmmaker and York University professor, and Tarek Loubani, an emergency room doctor from London, Ont., were arrested on Friday.

Justin Podur, a mutual friend of the pair, confirmed the identities of the two men and said Loubani called him on Friday evening to say thatthey had been detained. However,Loubani did not provide any information on where they were beingheld or if they would be facing charges.

Gen. Abdel-Fattah el-Sissi, the country's military chief, said Sunday that the crackdown, followed by a state of emergency and a nighttime curfew imposed in Cairo and several other flashpoint provinces, is needed to protect the country from "civil war." El-Sissi has vowed the military would stand firm in the face of the rising violence but also called for the inclusion of Islamists in the post-Morsi political process.

No claim of responsibility for attack

Sinai, a strategic region bordering the Gaza Strip and Israel, has seen almost daily attacks since Morsi's ousterleading many to link the militants there to the Muslim Brotherhood, the Islamist group from which Morsi hails.

Egyptian military and security forces have been engaged in a long-running battle against militants in the northern half of the peninsula.

Al-Qaeda-linked fighters, some of whom consider Morsi's Brotherhood to be too moderate, and tribesmen have used the area for smuggling and other criminal activity for years and have on occasion fired rockets into Israel and staged cross-border attacks. A year ago, 16 Egyptian border guards, a branch of the army, were slain in Sinai near the borders with Gaza and Israel in a yet unresolved attack that is widely blamed on militants.

In Monday's attack, the militants forced the two vehicles to stop, ordered the policemen out and forced them to lie on the ground before shooting them, the officials said. The policemen were in civilian clothes, said the officials, speaking on condition of anonymity because they were not authorized to talk to the media. There was no immediate claim of responsibility for the attack, which also left two policemen wounded.

The officials initially said the policemen were killed when the militants fired rocket-propelled grenades at the two minibuses. Such confusion over details in the immediate aftermath of attacks is common. Egyptian state television also reported that the men were killed execution-style.

Detainees in prison convoy riot

The killings, which took place near the border town of Rafah, compound Egypt's woes a day after police fired tear gas to free a prison guard from rioting detainees, killing at least 36.

In the deaths Sunday of the prisoners captured during clashes the past couple of days in Cairo, officials said detainees in one of the trucks transporting them had rioted and managed to capture a police officer inside. The detainees were in a prison truck convoy of some 600 prisoners heading to Abu Zaabal prison in northern Egypt.

Security forces fired tear gas into the truck in efforts to free the badly beaten officer, the officials said, adding that the people killed died from suffocation. Those officials also spoke on condition of anonymity because they were not authorized to speak to journalists.

However, the officials' version of event contradicted reports about the incident carried by state media. The official website of state television reported that the deaths took place after security forces clashed with militants near the prison and detainees came under fire while trying to escape. The official MENA state news agency also said the trucks came under attack from gunmen.

State media also said the people killed and the gunmen belonged to the Brotherhood. The officials who spoke to AP said some of the detainees belonged to the Brotherhood, while others didn't. The differences in the accounts could not be immediately reconciled.

The Brotherhood said in a statement that it blamed the military chief, el-Sissi, and Interior Minister Mohammed Ibrahim who is in charge of the police, for the attack Sunday. The group also called for an international inquiry into the deaths.

Possible ban on Muslim Brotherhood

Along with the state of emergency imposed after Wednesday's crackdown on the pro-Morsi sit-ins in Cairo and ensuing street clashes across the country, the military-backed interim government has also begun taking harsher measures to cripple the Brotherhood.

Security forces arrested hundreds of Muslim Brotherhood members early Sunday in raids on their homes in different cities, aimed at disrupting planned rallies to support Morsi. The cabinet also held an emergency meeting to consider banning the group.

A possible banwhich authorities say would be implemented over the group's use of violencewould be a repeat of the decades-long struggle between the state and the Brotherhood. It also would drain the group's financial resources and allow for mass arrests of its members. That likely would diminish the chances of a negotiated solution to the crisis and push the group again underground.

The Brotherhood has shown no signs of backing down though.

Under the banner of an anti-coup alliance, the group held protests Sunday, though many appeared smaller in scale than others held in recent days. In the coastal city of Alexandria, protesters clashed with residents. In the southern city of Assiut, security forces fired tear gas to disperse hundreds rallying in front of a mosque.

"They think they can end the movement," said Muslim Brotherhood senior member Saad Emara. "The more killings, the more people join us."

However, the government blames Islamists for a series of attacks on churches and police stations, increasing public anger against the group.
