Hello, I'm Joe Macintosh with the BBC news.

The French authorities will fly a piece of aircraft debris from an Indian Ocean island to France later today where it will be examined to see if it comes from a missing Malaysian airliner. Experts say it appears to be a wing component from a Boeing 777. Jennifer Park reports from Kuala Lumpur.

"Malaysia's Prime Minister Najib Razak says initial reports on the debris show it was very likey from a Boeing 777 but that is too early to speculate whether it belongs to MH17 until investigators can examine it. One Malaysian team has been sent to where the debris was found and another to the French city of Toulouse for the inspection. Officials say it may be several days before they have any answers."

A top Australian official has told the BBC he's increasingly confident that the wreckage found in Reunion is from the missing Malaysian airliner. Martin Donald heads the Australian Transport Safety Bureau which is leading the search for the plane in the Eastern Indian Ocean. He said he still believed the search would eventually find the passenger plane.

"The analysis that we've done with the satellite data is highly reliable, and the search vessels, equipment and cruise we have had on the Indian Ocean, covering the area very throughoutly also are of high quality highly reliable. So we think we are looking into right place to a high degree of certainty and we are confident that we have the quality research to cover that area and find the missing aricraft."

The British government's Emergency Committee will meet today to discuss the crisis over migrants trying to enter the country from France through the Channel Tunnel. Lucy Williamson joined migrants at Calais as they attempted to reach the UK.

"After dark, the nature of Calais's challenge becomes clear. Hundreds of migrants are walking together along the highway that leads to the tunnel site. Toether they need to cross several fences and avoid security patrols. Well before midnight, groups of several dozens were struggling under the freshly-repaired fencing along Calais's railway line to reach the site. Some here have been discouraged by the growing number of police and television cameras, but their long-term goals remain."

A Palestinian toddler has been killed in a fire in what appears to have been a deliberate attack on his family's house in the west bank allegedly carried out by Jewish settlers. The 18-month-old died when the house in south Nablus was doused with petroluem-set light. Local residents said Jewish settlers scrawled graffitis on the walls, including the word "revenge" in Hebrew.

A white American police officer who shot died an unarmed black man early this month has pleaded not guilty to murder. Ray Tensing, a university of Cincinnati policeman has been charged with killing Samuel Dubose, who was shot in the head after being stopped for a minor traffic offense. Video footage from a camera worn by Mr Tensing contradicted his initial account that he had been dragged along by the car.

Scientists in United States and South Korea have developed a tiny robot similar to an insect that's fitted with a spring and can jump on water. They hope the device will be used to develop new ways of monitoring pollution in waterways. Victoria G reports.

"Jumping, flying and hovering insects are a source of huge inspiration for Bio-roboticists. This team discovered how one particular insect, the water strider, managed to spring up from a quartic surface. The team found that the insects pushed off with a downward force that exceeded the surface tension. That's the force that glues the water surface molecules together. To mimic this, they designed their robot with a spring built into its waver thin V-shaped body. When it jumps, the spring releases and the insects-like legs are pushed downward, propelling it from the surface of the water."

Police and US Coastguard in Portland, Oregon have been involved in a dramatic operation to help a ship involved in Arctic oil drilling get pass environmental protesters to leave port.
