A suicide bomber launched his explosive-laden car in one of two buses carrying soldiers off in the turbulent region of Egypt north Sinai Wednesday , killing nearly a dozen and injuring dozens of others, security officials and military said. 

CAIRO - A car suicide bomber hit a convoy of buses outside Egyptian soldiers in the Sinai Service Wednesday , killing 11 people and wounding 37 in the latest accelerated the attacks blamed on Islamist militants sympathetic wave to ousted egyptian president Mohammed Morsi .

The mounting insurgency in the restive Sinai sent the security and intelligence services scrambling for new tactics to thwart future attacks and protect themselves amid signs of rampant violence in other parts of Egypt , especially the capital is Cairo.

Among the attacks that have raised the alarm was the murder of a security guard supervisor who monitors Islamist groups , shot in the neighborhood of Cairo Sunday evening. At dawn Wednesday , assailants threw a grenade at a police checkpoint in the northern suburbs of Cairo , injuring four policemen , according to security officials . The attackers fled, officials said .

The violence has prompted a reshuffle within the ranks of security agencies , including the hunt for possible Islamist "moles" among officials distrust that the Muslim Brotherhood Morsi is linked to violence - a charge the group denies .

In addition, the security guards that have been removed or transferred key positions for a year the chair Morsi recovered , according to officials , who spoke on condition of anonymity to discuss the work of the agencies.

Soaring militant violence brings us back to the Islamic insurgency in the 1980s and 1990s, when militants , mainly based in the government of southern Egypt - Hosni Mubarak fought to install a purist Islamic state. The activists were finally crushed by a ferocious repression of security that helped consolidate the state police under Mubarak .

For several months , the army conducted raids intensified in towns and villages in northern Sinai , the hunt for militants.

In Wednesday's attack , a convoy of four buses carrying army soldiers take breaks battlefield along a main road linking the provincial capital el- Arish to Rafah on the border with Gaza. The soldiers in the convoy belonged to the 2nd Field Army , which is doing most of the fighting in the anti- militant campaign of Sinai.

A car loaded with explosives two people in it struck the main bus and exploded , military spokesman Ahmed Mohammed Ali said in a statement.

Military commander General Abdel Fattah al- Sisi attended a ceremony as the bodies of soldiers were purchased at a military airfield in Cairo.

This treacherous attack only increases our determination , and we will not allow those who raise arms to destroy this nation or repress its people," he said gave condolences to the families of the dead, according to a military statement .

It was not claimed responsibility for Wednesday's attack , but car bombs are a signature method by groups linked to or inspired by al - Qaeda militants.

The northern region of Sinai, on the border with Gaza and Israel was stirred for years. But the attacks have become more frequent, deadly and bolder since the ouster of Morsi . In August , gunmen fired 25 police conscripts minibuses in the Sinai and killed. There have also been a number of suicide attacks - a tactic rarely seen in the 1990s the Islamic insurgency .

The violence has also moved to other parts of the country , including Cairo and all Egypt .

In September, Interior Minister Mohammed Ibrahim survived an assassination attempt by a suicide car bomb in Cairo. The same month , suspected militants fired rocket -propelled grenades at the main satellite ground station in Maadi , a southern suburb of Cairo.

In a video posted online Tuesday, a militant group , Ansar Jerusalem, claimed responsibility for the murder of Sunday the security officer , police Lieutenant Colonel Mohammed Mabrouk . The group said that the killing was in retaliation for the recent arrest of supporters Morsi women.

The group previously claimed responsibility for the assassination attempt against Ibrahim and other attacks .

The new insurrection and repression against her place in the middle of the struggle between the Islamist supporters of Morsi and the new army-backed government since the overthrow of the first freely elected president of Egypt in a coup in July invited by massive protests against him 3 .

Brotherhood led protests demanding his reinstatement, but their rallies fell under the weight of a fierce crackdown by security forces that killed hundreds of supporters Morsi .

The clashes erupted Wednesday between protestors pro - Morsi Al - Azhar and the police after students tried to block the main street outside the campus. Police fired tear gas to disperse the students, who were protesting against the arrest of two dozen colleagues at a rally earlier in the day. A student was killed in the clashes , according to the head of emergency services Ahmed el- Ansari .

Thousands of Brotherhood members , including senior officers, have been arrested, some of them , including Morsi - are on trial on charges of incitement to violence.

The Brotherhood denies any connection to violence. However , supporters of Morsi have been blamed for a series of reprisal attacks soon after the crackdown began , particularly attacks against churches and government buildings. Brotherhood leaders say they are not linked to militant groups in the Sinai , but some leaders publicly warned that the ouster of Morsi trigger a reaction of extremists in the peninsula Brothers .

Egyptian Military officials and senior security said Mabrouk murder and assassination attempt against Ibrahim September sparked a series of emergency officers of security agencies and intelligence meetings to decide new tactics to fight against the rising number of attacks.

Already , they have stepped up security at military bases with sand barriers erected doors, new watchtowers, security cameras and devices jammers to disable remote controlled bombs signals, officials said . Officers of the Directorate of National Security and the General Intelligence Agency told to take extra security precautions , including changing the registration of their cars or new car purchase plates. Files on the personal data of employees were under enhanced security, they said.

Another objective of the new policy, officials said , is to measure the extent of participation of Brotherhood leaders , including those detained in the wave of attacks . A major concern , said officials , is that the Muslim Brotherhoodleaders had access to sensitive information and records for the year Morsi was in power.

Officials said they plan to enhanced monitoring visits received by the leaders of the Muslim Brotherhood in prison and building specialized teams monitoring and infiltration of Islamist groups.

Agents with expertise in Islamic militancy that have been removed from the Intelligence Branch during the presidency of Morsi were approached with offers to return to work , they said .
