The Yemeni government and Shiah Houthi rebels have signed an UN-brokered deal to try to end a political crisis that had seen the rebels take over key parts of the capital Sanaa. Under the accord, a new government will be formed within a month. The Houthis and the Southern Movement Herak have three days to present their candidates for a prime minister. But the Houthis have not yet signed a part of the agreement that calls for a ceasefire to begin. Sebastian Usher reports.

During the day the Houthis rebels took other ministries and military buildings raising fears of an all-out coup. It may have been more of a show of force when they have been threatening for some time. The security forces offered little or no resistance. The deal was waiting to be signed at the Presidential Palace. It wasn't clear if the Houthis advance would scupper the agreement or it's essentially a part of its choreography. The result for now at least is a big political change in Yemen with the Shiah Houthis potentially gaining an unprecedented say in government at the expense of their main rival the Sunni Islamist movement al-Islah.

Thousands of Russians have marched through the center of Moscow in their first major protest against Russia's alleged involvement in the Ukraine conflict. In Ukraine itself, the government had said its military forces will not pull back in the east of the country until Russian troops leave. Sierra Reins report.

As they march through central Moscow, the protestors chanted 'No to war and hands off Ukraine.' Many carried the yellow and blue Ukrainian national flag alongside the Russian colours in a show of solidarity. Others had signs asking Ukraine to forgive them. The Kremlin has always denied that it's supporting the pro-Russia rebels in east Ukraine or sent in its own servicemen there to fight alongside them. But people in this crowd don't believe that.

The authorities in Sierra Leon have decided not to extend the three-day Ebola lockdown which is due to end in a few hours. More than 90 bodies have been retrieved during the lockdown and over 100 people have voluntarily reported themselves to the health authorities. Our correspondent in Freetown Umaru Fofana says the confirmation that the curfew will finish shortly was greeted with enthusiasm.

One is broke initially that the extension was being considered. There was a lot of mumbling around with people saying we are running short of stock of food and all of that. And when once this went out again, people have thronged the streets in the eastern Freetown singing 'Jesus, Ebola is finished. Jesus, Ebola has ended.' Lots of people in the east of Freetown are on the streets as I speak to you now. Umaru Fofana reporting.

Nigeria's National Union of Teachers has called for a further delay in the start of the school term because of the Ebola outbreak. Pupils are due to return to lessons tomorrow. The head of the Union Michael Olukoya said safety measures to contain Ebola were not in place. President Goodluck Jonathan dismissed the call for a postponement.

A global day of protest against climate change has culminated in New York City where tens of thousands people marched to demand urgent action. The demonstrators included celebrities, scientists and world leaders. Among them was the UN Secretary General Bam Ki-moon. Our correspondent Mack Migra was there.

They are all hoping here to send a message to the politicians; the heads of the government will come in to the work on Tuesday; to send a message that there is big popular support in the world for action, rapid action on climate change. And they think that by demonstrating on the streets there, by having perhaps the biggest climate march in history, it will be able to increase the pressure to drive towards a new global deal to be signed at the end of 2015 in Paris.

One of the world's biggest car manufacturers General Motors is recalling hundreds of thousands of vehicles because it has identified an increased risk of fire from using the brakes.

The rival candidates in Afghanistan's presidential election have signed a power sharing deal, ending months of arguments over alleged fraud.

A NASA spacecraft is about to enter into orbit around Mars after a 10-month journey of over 700 million kilometers. The Maven explorer will circle the planet to study its atmosphere. Its main task is to find clues as to why Mars went from being wet and warm to cold and dry billions of years ago. Scientists believe the red planet initially had a thick atmosphere which has since thinned.
