Hello, I'm Tom Sandars with the BBC News.
The challengers for the US presidency have been addressing large rallies as they try to maximize their support on Super Tuesday. Eleven US states are choosing Democratic and Republican Party candidates for November's election. The Republican Donald Trump and the Democrat Hillary Clinton are hoping wins today will allow them to pull decisively away from their rivals. James Cook reports. “Polls suggest Donald Trump will sweep the board in almost all of the 11 states which are in play despite the hostility of many people inside his adopted party. Having built his support on divisive rhetoric about banning Muslims from entering the US and building a wall on the Mexican border, Mr. Trump today tries to present himself as the unity candidate. The exception to Mr. Trump’s expected dominance may be here in Texas, the home of Senator Ted Cruz who insists he is the only credible conservative alternative to the property tycoon, a claim disputed by another Senator Marco Rubio of Florida.” Mrs. Clinton's only rival for the Democrats' nomination Bernie Sanders will be hoping to win in his home state of Vermont.
NATO's most senior commander in Europe has accused Russia of helping the Syrian government to create a refugee crisis deliberately as a weapon of war. General Philippe Breedlove told a Senate Committee in Washington that he could see no reason for Moscow and Damascus to use indiscriminate weapons against civilians in Syria other than to displace people. “The Russians are using almost no precision weaponry. Their weaponry is imprecise and dropped in a large quantity and again I don't know what military utility that would have other than to get people displaced and on the road and into someone else's problems there.”
The Head of FBI has accepted that forcing Apple to unlock an iPhone linked to a terror attack could set a legal precedent. James Comey told a congressional committee that Apple's iPhone encryption stopped law enforcement agencies from gathering evidence. Apple says creating software to unlock the phones would weaken the security of hundreds of millions of devices.
The Bolivian President Evo Morales has begun legal action against former girlfriend demanding his son he thought to have died nine years ago.

Mr. Morales says Ms. Zapata has been given five days to present the boy to the authorities.
Officials in Jordan say the security forces have killed several militants during raids to arrest suspected Islamists in the northern city of Irbid near the border with Syria. The government described it as one of the largest sweeps against hardline Islamist groups in recent years.
Scientists say they've identified for the first time a gene responsible for grey hair. The researchers say the gene called IRF4 is involved in regulating melanin, the pigment being hair color, as well as the color of the skin and eyes. One of the scientists Dr Kaustubh Adhikari from University College London says further research could make it possible to target proteins responsible for greying. “We think that eventually you could have a bill or you could have a lotion for your skull about something that you might use for this purpose. That's all speculative in the future. We have to do much more study before we can do that.”
