Chad is shuttering Qatar's embassy and giving its diplomats 10 days to leave the country, accusing the Gulf Arab state of trying to destabilise the central African nation via its northern neighbour Libya, it said on Wednesday.
It is not the first African state to move against Qatar following its rift with other Gulf states including the United Arab Emirates, Bahrain and Saudia Arabia as well as Egypt.
Senegal said this week that it had reinstated its ambassador to Qatar after having recalled him three months ago, in a bid to encourage a peaceful resolution to the feud.
"In order to safeguard peace and security in the region, Chad calls on Qatar to cease all actions that could undermine its security as well as those of the countries of the Lake Chad basin and the Sahel," the foreign ministry statement said.
It did not provide any details to support the accusation.
The statement from Chad's foreign ministry added that it would close its diplomatic mission in Doha and recall all personnel.
Qatari officials were not immediately available to comment.
