CAIRO – ****** on a speeding motorcycle opened **** outside the famed Giza Pyramids on the outskirts of Cairo early Wednesday, ******* two ****** officers in a rare ****** near one of the country’s top tourist attractions, authorities said.

The ****** comes as Egypt tries to rehabilitate its vital tourism industry, which accounted for as much as 20 per cent of foreign currency revenues before its 2011 revolt that toppled autocrat Hosni Mubarak and later years of turmoil.

From a high of 14.7 million tourists in 2010, Egypt has had an average of around 9 million a year since, though officials say tourists slowly are coming back. Government officials say the tourism industry saw revenues jump to $4 billion in the first half of this year, compared to $1.9 billion in the same period last year.

The ****** opened **** on a ****** vehicle at the back of the Giza Pyramids plateau on a main highway that leads to southern Egypt, wounding the two tourism ****** officers, a security official said. They **** later of their wounds in the hospital, said the official, who spoke on condition of anonymity because he was not authorized to brief journalists.

Egypt’s state MENA news agency said the ****** fled and that an ************* was underway. MENA quoted an antiquities official in the area, Kamal Wahid, as saying the ****** was 5 kilometres (3 miles) away from the main entrances to the pyramids. The location of the ****** could not be immediately reached by journalists.

Egypt sees regular ******* on its security forces as it struggles with the low-level Islamist insurgency, mostly in the lawless northern Sinai Peninsula following the 2013 military ouster of elected Islamist President Mohammed Morsi. Typically though, security forces are the targets of the *******.

But the ******* lately have inched closer to the capital, mostly targeting individual security agents but have also included near-daily small ******** in public areas. One ******* ****** a ****** officer on a bridge in Cairo’s upscale island of Zamalek.

An earlier wave of Islamist insurgency peaked in 1997 with a bloody ****** against tourists in a temple south of Egypt that left more than 60 tourists ******. So far, however, tourist sites have not been targeted.

The ***** in ******** in the last two years was accompanied by a crackdown on the 87-year old ****** Brotherhood, from which Morsi hails, and other Islamists. Militants say the ******* are meant to avenge the crackdown. Sinai-based Ansar Beit al-Maqdis – which has claimed most of the major ******* in Egypt – has pledged allegiance to the Islamic State extremist group fighting in Iraq and Syria and has declared itself to be the group’s Sinai Province.

The government blames the Brotherhood for the ********, a charge the group has denied. But increasing pressure on the group appears to have caused a schism within, between those who openly call for a direct confrontation and others who call for peaceful means. There also has been a rise in ******* against government institutions, electricity poles and recently the ****** ******** of three judges.

On Wednesday, a soldier was shot **** by a sniper while manning a checkpoint in Sheik Zweid, a town south of provincial capital of northern Sinai, el-Arish, an official said. He also spoke on condition of anonymity because he was not authorized to speak to journalists.

Reflecting an intention to keep up the crackdown, the government proposed Wednesday imposing penalties of no less than a year in prison and a fine for anyone who does not report owning explosives.
