Nigerian army escalates Boko Haram offensive

ABUJA. Nigerian soldiers today sealed roads heading out of a key northeastern city, blocking supply routes to remote towns where Boko Haram Islamists have taken power as a massive offensive against the insurgents spreads across the region.The campaign against Boko Haram, which has said it wants to create an Islamic state in northern Nigeria, is aimed at re-establishing Nigeria’s “territorial integrity,” the military said after a state of emergency was declared in three areas.The assault has included air strikes on Boko Haram strongholds in remote parts of northeastern Borno state, and has spread to the state capital Maiduguri, the insurgents’ traditional home base — which residents said Sunday had been blockaded.“There is a huge build-up of trucks loaded with essential commodities... along the Baga road on the way out of Maiduguri to the northern part of the state,” said resident Ibrahim Yahaya.“The drivers said they have been prevented by the military from going northward,” he told news agency AFP by email.The phone network in Borno has all but collapsed since President Goodluck Jonathan on Tuesday declared a state of emergency there and in two neighbouring states, Adamawa and Yobe.Defence spokesman Chris Olukolade said in a statement Saturday that Islamist fighters who are on the run amid the offensive are scrambling for key supplies like fuel.He urged residents to report anyone trying to buy large quantities of fuel.The supply shortage has begun to bite in the town of Gomboru Ngala, on the border with Cameroon, where some Borno residents have fled to escape the air raids.“Trucks bringing in goods from Maiduguri have ceased since last week,” said resident Grema Babagoni.He said the supply shortage has pushed prices up by as much as 25 per cent.“If the blockade continues for some time we may completely run out of supplies,” he told AFP.Some residents in Gomboru Ngala have been contactable because they use Cameroonian phone lines.The town has received an influx of people fleeing the nearby Marte district, one of the areas where Boko Haram chased out the government and removed Nigerian flags.Marte has been among the areas targeted by air strikes, residents have told AFP.Meanwhile, the offensive is escalating in Maiduguri, the city where the Boko Haram insurgency was born.
