ABUJA (Reuters) – A group of Islamic militants, Boko Haram, killed at least 60 people in Rannah, northeastern Nigeria, on Monday, the day after the military abandoned, Amnesty International and security sources said Friday.
The attack on Rann, home to a camp with tens of thousands of people resettled by Islamic rebels, was one of the bloodiest.
Two weeks after Boko Haram had overcome the same city, he left the Nigerian soldiers and pointed out that it would appear again as a force capable of absorbing the army base.
Bloodshed is a challenge to President Muhammad Buhar because he elected the second consecutive four-year term on 16 February, which was partly promised to restore security.
A Nigerian army representative denied that the troops had left the city and that Boko Haram had killed people.
Both attacks have helped some 40,000 people flee, of which 30,000 – next to Cameroon, according to relief agencies.
"This attack on civilians who have already been displaced from the bloody conflict may be war crimes," said Osai Ojigh, Amnesty's Nigerian director.
"Witnesses told us that Nigerian soldiers left their days before the attack, demonstrating that the authorities were totally unable to protect civilians."
Two security sources Reuters said that Nigerian troops returned to Rannah after the first attack on 14 January with Cameroon troops.
After Cameroon's citizens returned to the border, Nigerian soldiers left because they did not have enough soldiers, weapons or equipment, sources said.
The next day Boko Haram arrived. The militants named the city ablaze and executed their senior and traditional leaders, leaving one alive as a witness, one of the sources said.
The video on Reuters tested the attack showed that people gathered their belongings and fled as the city burned.
The Nigerian army soldiers returned to the beach and helped bury some of the dead when Boko Haram left, Amnesty International and security sources.
The rise of attacks in the northeast with Boko Haram and its now strongest Islamic country in West Africa is ready for the presidential election unclear.
Despite violence, Vice-President Yemi Osinbay said on Tuesday: "The current rate of return of internally displaced persons and refugees is encouraging, and this is due to improvements in security in many areas that were once completely out of bounds".
