Kenyatta's spokesman said that two leaders had spoken by phone on Sunday.

Kenya's President Uhuru Kenyatta has told Burundi leader Pierre Nkurunziza he should postpone a presidential election due next month after last week's failed military coup, Kenyatta's spokesman said on Monday.

Manoah Esipisu said the two leaders, whose nations belong to the East African Community (EAC) common market, had spoken by phone on Sunday. Kenyatta's counterparts in the region shared his view, he added.

Regional leaders want the election date changed from June 26 to create a "conducive environment" but the vote should still be held within the current electoral cycle, which comes to an end in late August, Esipisu said.

The landlocked east African nation has been plunged into crisis since Nkurunziza pushed for a third term of office, a move his opponents say breaks the constitution and a 2005 peace agreement that ended an ethnically driven civil war.
