Rwanda will retaliate if it suffers further attacks from the Democratic Republic of Congo, its foreign minister says, after accusing the neighbouring country of firing shells across the border earlier this month.
DR Congo summoned Rwanda's ambassador and suspended RwandAir flights to DR Congo over the weekend in response to what it said was Rwandan support for M23 rebels carrying out a military offensive in its eastern borderlands.
Rwanda denies the claims and has in turn accused DR Congo's army of fighting alongside the Democratic Forces for the Liberation of Rwanda (FDLR), an armed group founded by ethnic Hutus who fled Rwanda after participating in the 1994 genocide.
"If attacks continue we will not sit idly by... Rwanda will have the right to respond to protect the security of the country, to protect the security of its citizens and we have the means to do that," Foreign Minister Vincent Biruta told reporters.
The clashes threaten to unravel relations between the two countries, which had improved since DR Congolese President Felix Tshisekedi came to power three years ago.
The M23 insurgency stems from the long fallout from the 1994 genocide in Rwanda.
