NIAMEY: Niger has extended a state of emergency in the south-eastern region of Diffa for three months after a series of attacks by Boko Haram, the government said on Friday. Attacks by Boko Haram since May have emptied the towns of Bosso and Yebi near Nigeria’s border in the Lake Chad region. Some 69,000 have fled, according to a report on Friday by the UN Office for the Coordination of Humanitarian Affairs (OCHA). “Despite the various extensions of the state of emergency in the region of Diffa and bloody setbacks inflicted on it, the Boko Haram sect still continues to have a destructive capacity as evidenced by the recent attacks in Bosso,” the government said in a statement. Boko Haram took the town of Bosso near the Nigerian border in June, in an attack that killed 30 Niger soldiers. It was the deadliest assault by Boko Haram since April 2015. Since then, Chad has sent troops to help Niger wage a counter-attack. The state of emergency, which the government hopes will allow it to beef up its presence in the region with troops and added security measures, will now run till October. It is the latest in a series of such declarations in the Diffa region since February last year. Boko Haram has been trying to establish an Islamic state obeying Sharia law in north-eastern Nigeria since 2009. The violence has since spread into neighbouring Niger, Chad and Cameroon. About 2.1 million people have been displaced and thousands have been killed during the insurgency.
