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.

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

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.
