KINSHASA, Democratic Republic of Congo — The Democratic Republic of Congo’s government cut internet connections and SMS services across the country for a second straight day on Tuesday as the country nervously awaited results from the weekend’s chaotic presidential election.

Both the opposition and ruling coalition said on Monday they were on track to win after a turbulent Election Day on Sunday, in which many Congolese were unable to vote because of an Ebola outbreak, conflict and logistical problems.

Barnabé Kikaya bin Karubi, a senior adviser to President Joseph Kabila, said internet and SMS services were cut to preserve public order after “fictitious results” began circulating on social media.

“That could lead us straight toward chaos,” Mr. Karubi said, adding the connections would remain cut until the publication of complete results on Jan. 6.
