NAIROBI/ADDIS ABABA - Fresh fighting between the Ethiopian army and a local militia in the northern Amhara region has raised concerns among residents for the safety of historic rock-hewn churches in the holy town of Lalibela. Fano militiamen over-ran Lalibela and Gondar, the second-biggest city in the Amhara region, for several days in August in Ethiopia's most serious security crisis since a two-year civil war in neighbouring Tigray ended a year ago. Lidetu Ayalew, an Amhara politician based in the United States who grew up near Lalibela, said he feared the churches could be struck and destroyed. "The churches risk being struck and destroyed due to careless firing of heavy weapons," he said in a statement on Monday. Fighting in Amhara killed at least 183 people in the first month of the conflict, the United Nations said in late August.
