Thousands have been killed and 700,000 displaced this year, after Rwandan troops and M23 rebels invaded eastern Congo.

After talks in Qatar, the two countries’ presidents said they were committed to an unconditional truce between Congo’s army and a rebel group that Rwanda denies backing.

In a surprise announcement from Qatar Tuesday the Democratic Republic of Congo and Rwanda jointly called for a cease-fire in an effort to end warfare between them after 30 years of fighting.
