BBC News. I'm John Shea. Armenia and Azerbaijan have accused each other of violating the latest humanitarian ceasefire over the disputed territory of Nagorno Karabakh within minutes of the truce coming into effect. Here's our Caucasus correspondent Rayhan Demytrie. This is the second attempt at a ceasefire to allow for the exchange of prisoners and the recovery of bodies. But just minutes after the new ceasefire went into effect at midnight on Saturday, the Armenian Defense Ministry spokeswoman announced that Azerbaijan was still firing artillery, shells and rockets and had launched an assault near a reservoir close to the Iranian border. Azerbaijan, in turn, accused Armenia of shelling in the direction of Jabrayil, one of the areas that Azeri forces had recently recaptured adjacent to the disputed Nagorno Karabakh region.
A landslide in central Vietnam has buried at least 22 soldiers, leading to a frantic search for survivors. Five dead bodies have been recovered from thick mud. Our Asia Pacific editor Celia Hatton has more details. Government reports a part of a mountain collapsed on top of a barracks in Vietnam's central Quang Tri province in the early hours of Sunday morning. One official said four or five landslides occurred one after the other, sounding like bombs. He said it now felt as if the whole mountain was set to collapse. Vietnam is experiencing its worst flooding in years. More than 60 people have already died in Quang Tri. The UN has warned that Vietnam is one of the countries most vulnerable to climate change.
Vigils and rallies will be held across France today in solidarity with the teaching profession following the Islamic murder of a teacher on Friday. Samuel Paty was beheaded after showing people's cartoons of the Prophet Muhammad in a civic lesson. The Education Minister Jean Castex called on everyone to support the teachers, saying it was vital to show national cohesion. Jean-Remi Girard is the president of the national union of school teachers in France. I'm not surprised that he showed the cartoons. It's something and many teachers do in France since the events with the Charlie Hebdo. And that's something nearly quite usual in order to speak about freedom of speech, about the secularism. And that's something many teachers do in our country.
Iran has welcomed the end of a long standing UN arms embargo, but has reiterated that it doesn't plan to go on a weapons buying spree.
