Hello, and welcome to NewsHour from the BBC World Service.
We are coming to you live from London.
I'm Rob Young and we start in Pakistan, where a powerful bomb blast at a railway station has killed 25 people and injured more than 40 others.
The authorities say a suicide bomber detonated their device as passengers were waiting to board a morning train in Quetta, the capital of Baluchistan in the South West.
Video footage shows scenes of chaos, with bodies lying among the debris and part of the station roof hanging down.
Abdul Jabbar, one of the people injured in the attack, described what happened.
I was going inside the station after buying a train ticket.
After two minutes, as I reached inside on the platform, there was a blast.
Two more people who were with me got injured.
There were more people with me.
God knows what happened to them.
Well, the separatist group, the Baluchistan Liberation army, said it was responsible for the blast.
The commissioner of Quetta, Hamza Shafakat, told reporters that the militants must be defeated.
