Algeria is cutting diplomatic relations with Morocco, Foreign Minister Ramdane Lamamra said on Tuesday at a news conference, accusing its neighbor of "hostile actions".
Morocco and Algeria have had strained relations for decades, mainly over the issue of Western Sahara, and the border between the two countries has been closed since 1994.
"The Moroccan kingdom has never stopped its hostile actions against Algeria," he said.
Morocco's Foreign Ministry could not be immediately reached for comment. King Mohammed VI has called for improved ties with Algeria.
