France's foreign minister was due in Rwanda on Thursday after talks in the Democratic Republic of Congo as part of efforts to prevent a regional escalation following the capture of the eastern Congolese city of Goma by M23 rebels and Rwandan troops.

France expresses its solidarity regarding the Democratic Republic of Congo and condemns actions by Rwanda in the country, French Foreign Minister Jean-Noel Barrot said on Monday.

France is pursuing a diplomatic solution to the conflict in the Democratic Republic of Congo. M23 rebels, reportedly backed by Rwanda, have seized the city of Goma. France emphasizes the importance of ending the conflict swiftly and is considering diplomatic measures over sanctions against Rwanda.

Paris has condemned an attack on its embassy in the Democratic Republic of Congo's capital, Kinshasa. The attack came amid demonstrations against the escalating conflict in the country's east.

France's foreign minister on Monday said an offensive by Rwanda-backed armed group M23 on the Democratic Republic of Congo city of Goma "must stop".

The United States, France and Britain pressured Rwanda on Sunday over its support for rebels rapidly closing in on eastern Congo's largest city, as government forces struggled to halt an offensive that has forced thousands of civilians to flee.

M23 militia fighters, alongside Rwandan troops, are pushing into the eastern DR Congo city of Goma, capital of the mineral-rich North Kivu province.

A rebel alliance claimed the capture of the biggest city in the Democratic Republic of Congo’s mineral-rich eastern region this week, pushing back against resistance from government troops backed by regional and UN intervention forces.

Many blame the United States, France and other allies for allowing neighboring Rwanda to fuel a conflict in the country’s east.

A conflict that has raged for decades reached a flashpoint this week when rebels backed by Rwanda marched on a key Congolese city in a bid to occupy territory and exploit minerals.

In 2012, when M23 rebels appeared poised to seize control of a major city in eastern Congo, western countries suspended aid to put pressure on Rwanda to withdraw its support.
