The US Secretary of State Chuck Hagel has said the US is rethinking its opposition to arming Syria's rebels. It's the first time a senior American official has openly acknowledged that the administration is considering providing weapons to the rebels, although no decisions have been made. Our state department correspondent Kim Ghattas reports.

The American Secretary of Defence Chuck Hagel said the US administration was considering a range of options including arming the Syrian rebels, but he made clear no decisions had been made. Last year President Barack Obama rejected a proposal by his then-Secretary of State Hillary Clinton to arm the rebels. But as the fighting drags-on in Syria, the debate about what the US should do has intensified in Washington, and with no appetite here for direct military intervention, many US officials increasingly feel that arming the rebels is now the least worst option. American allies like Qatar and Saudi Arabia are already providing weapons to various groups fighting President Bashar al-Assad's forces.

President Obama has arrived in Mexico for talks that are expected to switch the focus of bilateral ties to job creation and trade rather than security issues and the war on drugs. Will Grant reports from Mexico City

As Mr. Obama touched down in Mexico City on his first visit since Enrique Pena Nieto took office. He was welcomed off Air Force One by the country's Foreign Minister Jose Antonio Meade and the US ambassador Antony Wayne as well as other members of the Mexican government military. President Pena Nieto was waiting for his guest at the National Palace for bilateral talks. In some way, Mr. Obama arrives with two separate agendas, one public, in which both sides have been keen to strengthen emphasis on the economy and trade; the other is private which is thought to include difficult questions about security and cross-border crime.

They could also break into servers located abroad, if they are being used to block services. The government said the use of these powers would be subject to the approval of a judge.
