David Cameron is pushing for an independent, international investigation into alleged atrocities during the Sri Lankan civil war to begin within a year as pressure mounts on the regime in Colombo.
The Prime Minister has personally sought the support of several fellow leaders for a United Nations Human Rights Council resolution authorising a UN-led probe.
As many as 40,000 civilians are estimated to have died in the final months of the Sri Lankan government's 26-year fight with Tamil Tiger separatists - which ended in 2009.
Both sides in the brutal conflict are accused of widespread human rights abuses - including executions and rapes of prisoners by state troops.
Farmed salmon should be sterilised to prevent them breeding with wild fish and introducing genetic weaknesses, experts have urged.
Millions of salmon escape from fish farms each year, and can get into wild spawning populations where they can reproduce and introduce negative genetic traits.
"Farmed salmon grow very fast, are aggressive, and not as clever as wild salmon when it comes to dealing with predators.
"These domestic traits are good for producing fish for the table, but not for the stability of wild populations". Lead researcher Professor Matt Gage said.
Armed rebels that have seized an oil port in eastern Libya have said that any attempt by government forces to attack a North Korea-flagged tanker loading oil at one of their occupied terminals would be like a "declaration of war".
Abb-Rabbo al-Barassi, self-declared prime minister of the movement, warned Libya's navy not to "harm" the tanker docked at Es Sider, according to a statement.
"Such a move would be a declaration of war," al-Barassi in the statement, which was sent to Reuters by a spokesperson.
Liberal Democrat leader Nick Clegg told delegates at his Party's conference today that he loved Britain and wanted it to stay in the European Union.
In his keynote speech, the Deputy Prime Minister also attacked Ukip, calling them the "acceptable face" of backward-facing politics.
ITV News political correspondent Romilly Weeks was at the conference in York:
Newborns freezing to death in hospital incubators, patients opting to be knocked out with metal bars for lack of anesthesia, surging cases of polio.
A new report published by charity Save the Children paints a dire picture of Syria's collapsing healthcare system.
The report, issued by charity Save the Children, said some 60 percent of Syria's hospitals have been damaged or destroyed since the start of the three-year-old conflict and nearly half of its doctors have fled the country.
In Aleppo, one of the worst-hit cities, only 36 of its 2,500 doctors remain.
The report says increasing numbers of children are suffering and dying from diseases that would have been previously treated or prevented.
Up to 80,000 children across the Syria have contracted polio, even though the illness was eradicated across Syria in 1995.
Over 140,000 people have died in the war, which started as a peaceful protest movement against President Bashar al-Assad and degenerated into civil conflict.
After a beautiful, sunny and warm day for most, things will change in the next 24 hours.
Tonight rain across northern regions will gradually ease. Behind the wet weather Scotland and Northern Ireland will turn colder with frost and possibly some icy spots.
Into tomorrow morning, a slow start for some with low cloud keeping it misty and murky in places first thing.
By the afternoon, a reverse of fortunes compared to today. It'll be the turn of the north to have the best of the brighter skies with plenty of springtime sunshine and just a light breeze.
Further south more cloud than today and temperatures will be a few degrees lower than of late.
Speaking in Hanover at the CeBIT 2014 trade fair, David Cameron announced that German and British Universities would be collaborating on research towards 5G mobile internet.
He told the conference:

With 4G, an 800 megabyte movie takes around 40 seconds to download; with 5G that would be cut to one second.
This is a prize that researchers all over the world are going for and so I am delighted to announce a new collaboration, between the University of Dresden, King’s College University in London and the University of Surrey.
Three world-leading universities working on 5G hand in hand – that is something to be truly excited about.
