While negotiations in Kampala are stuck, despite the call from ICGLR member states to find a solution within the coming 14 days, Rwanda has more and more difficulties to hide its "go to war" agenda. Some might say this is just another show of force demonstration by Kigali regime who faces more and more difficulties domestically.
Let's hope it is so:

Regional powers fear Rwandan invasion of DR Congo

Southern African nations Saturday, September 14, expressed concern at the growing number of Rwandan troops on the border of the Democratic Republic of Congo and said it hoped an invasion was not imminent.

A statement from the Southern African Development Community (SADC) regional body said it was concerned "at the deployment of Rwandan troops along the common border" and "expressed the hope that Rwanda is not contemplating to invade."

Issued from a summit in Namibia attended by Congolese President Joseph Kabila, the statement called on the country's neighbors to "contribute to peace, security and stability of the DRC."

Congolese troops backed by a special United Nations force launched a fresh assault against M23 rebels late last month in DR Congo's north east.

Rwanda is facing elections this month (September) and the regime has to demonstrates that FDLR threat is still present. So several grenades also blew up in Kigali... The worst of us would even go as far as saying that several in RPF are trying to clear huge populous areas in Kigali to build malls are the ones behind those attacks...
Make up your mind.
