President Obama has praised the leadership of the Burmese President Thein Sein during historic talks at the White House. Mr Obama for the first time called the country Myanmar, the name adopted by the military rulers in 1989. And he hailed the country's political and economic reforms. Paul Adams is in Washington.
I think what's interesting was a couple of things. One, President Obama's demeanour. It was very serious and very sober, no kind of warm embrace here. I think the president is acutely conscious that there are people in Washington and elsewhere who think that a visit like this is premature. And he also said, President Obama said, that although President Thein Sein was making what he called ‘genuine efforts to solve ethnic conflicts, he did say that violence against Muslims in Myanmar, as he called it, must stop.
Iraq has suffered one of the worst days of sectarian violence in years with more than 70 people killed in car bomb attacks across the country. The majority of the victims in Baghdad and Basra were thought to be Shia Muslims. Caroline Hawley reports.
Most of the explosions were in Baghdad at restaurants, open-air markets and a bus station. Tensions between Sunnis and Shiites are now running so high that some fear a return to the all-out conflict of 2006 and 2007.
A grim-faced Prime Minister Nouri al-Maliki blamed militants of exploiting Iraq’s current political instability, which had led, he said, to sectarian chaos with the links beyond the country's borders. It was a clear reference to Syria where Iraqis are now fighting on both sides of the civil war.
The Russian security services say they’ve foiled a plot to carry out an attack on Moscow, killing two of the three suspects. From Moscow, here's Daniel Sandford.
The National Anti-terrorism Committee said the three men were Russian citizens, who they believed had been trained in Afghanistan or Pakistan. They were suspected of planning an attack on Moscow. Following an intelligence lead, special units of the FSB surrounded a house in Orekhovo-Zuyevo, a city about 90km east of Moscow. They say that when the men inside were asked to surrender, they opened fire. Two of the suspects were killed in the subsequent shoot-out; one was detained.
There's been fighting in the east of the Democratic Republic of Congo between the M23 rebel group and the Congolese army. The rebels attacked an army position north of the city of Goma. A BBC correspondent says he’s seen people fleeing. The clashes are the first since the rebels withdrew from Goma in December.
The Nigerian military says it's taken the five strongholds of the Islamist group Boko Haram in the north-eastern Borno state. The Ministry of Defence also said it had arrested 120 Islamists in Maiduguri, the state capital.

A gunman in Israel has shot dead four people before killing himself in a bank in the southern city Beersheba. The attacker, a former paramilitary border policeman, was apparently enraged that the bank had refused to grant him an overdraft. The Israeli Prime Minister Benjamin Netanyahu described the incident as a "great tragedy".
One of the world's biggest internet companies, Yahoo, is buying the social media website Tumblr for more than $1bn. Yahoo hopes it will now be able to attract younger users in its battle with rival firms such as Google and Facebook. Rory Cellan-Jones reports.
The aging web giant left flat-footed by the arrival of social media has been trying to reach new audiences under the leadership of a new boss, Marissa Mayer. She used her own Tumblr page to promise, in her words, “not to screw it up”. Yahoo now has to show it can continue to increase the website's audience and make money. This kind of deal can pay off or it can prove a costly disaster. As when AOL bought the social network Bebo for nearly $850m and sold it for less than $10m.
In London, shares have closed at their highest level for 13 years in line with trends on stock markets in the United States and Germany. Although the economy remains weak, the main FTSE index ended the day up 32 points at 6,756. Analysts said investors were putting their money into stock markets because low interest rates have made the return on bonds unattractive.
