Government troops are taking up positions outside a port in the far north of Mozambique which was captured by Islamist extremists last week in the latest escalation of the insurgency in the southern African country.
Hundreds of reinforcements have been rushed into position around the port in the town of Mocímboa da Praia.
The facility, which is close to the site of natural gas projects worth about $60bn (£45bn), fell on Tuesday when marines who had resisted several hundred militants ran out of ammunition and were forced to withdraw.
