1 Principal carjacked

The principal of Aurukun's only school has been carjacked and threatened with weapons for the second time in two weeks, sparking warnings that teachers could again leave the Queensland town. Police say a group of armed teenage boys confronted the man and his wife as they returned home from visiting colleagues on Saturday night. They weren't hurt but their government car was stolen and taken on a joyride before it was bogged outside the Cape York town. Three teens have since been charged. The principal was also carjacked by a group of teens armed with an axe earlier this month. Senior state government officials will fly to the community today.

2 Submarine helps search

Egypt sent a submarine to join the hunt for the flight recorders from the EgyptAir jetliner that crashed in the Mediterranean and killed all 66 people aboard, while hundreds of Coptic Christian mourners filled a church in Cairo to pray for their relatives among the dead. Mounting evidence pointed to a sudden and dramatic catastrophe that led to the crash of Flight MS804 from Paris to Cairo, although Egyptian President Abdel-fattah al-Sissi said it "will take time" to establish what happened aboard the Airbus A320.

3 Sanders ups battle

Democratic presidential candidate Bernie Sanders has cranked up his fight with party leaders, backing a challenger to the Democratic National Committee's chairwoman Debbie Wasserman Schultz and accusing the party's establishment of trying to anoint Hillary Clinton as the nominee for president. Sanders told the ABC that Americans should not have to choose between "the lesser of two evils" in the November election.

4 Manhunt after cop shot

A manhunt was underway for a suspect who shot and killed a police officer during a traffic stop in central Massachusetts, authorities said. Auburn police Officer Ronald Tarentino was shot after stopping a vehicle on a residential road, Chief Andrew Sluckis said. The vehicle's occupant then fled the scene, Sluckis said. Auburn is about 70km southwest of Boston.

5 Pressure on acting President

Thousands of demonstrators took to the streets of Brazil's two biggest cities to protest against acting President Michel Temer, trying to keep up pressure on his interim administration only 10 days after he was sworn in. A march in Sao Paulo headed toward Temer's residence, but police blocked roads near the house and the interim president left for Brasilia hours earlier. Organisers estimated 2000 people participated. In Rio de Janeiro, about 1000 protesters staged a march calling for Temer to resign. Some protesters want suspended President Dilma Rousseff back, others want elections.

6 Loach wins top prize

Veteran British director Ken Loach won his second Palme d'Or at the Cannes Film Festival for I, Daniel Blake - a stark portrayal of a disabled man's struggle with the crushing benefits system in northern England. The 79-year-old was presented the festival's top prize by actor Mel Gibson at a ceremony on the French Riviera.

7 Divine intervention

A Spanish priest says he has given up hope that local authorities in his parish of Xestoso in the northwest of the country will fix the potholes in the roads so he has asked for divine intervention. Luis Roldan Patino celebrated Mass on a pitted road and splashed holy water to bless it. Each pothole is now marked with a wooden cross on the roadside so drivers can slow down before hitting them, he said. Roldan Patino said the authorities are "blind to the situation and we feel totally abandoned".

8 Jump death accident

A Canadian Base jumper's death in Idaho has been ruled an accident, and investigators say they found a hole in her pilot chute. The Times-News reports 34-year-old Kristin Renee Czyz of Calgary packed her own parachute before she jumped from Perrine Bridge on May 14. Investigators found a hole in her pilot chute, which is supposed to pull the main parachute from its pack. They also found a broken zipper on her harness. Boaters pulled her body from the Snake River, attempted CPR and met up with emergency responders.
