Thousands of local people and aid workers are fleeing the Congolese city of Goma after officials said a second volcanic eruption could hit with little or no warning. Many people headed out of town on foot, with huge bundles on their heads while others fled by car, creating traffic jams across the city.<br />''<br />''Ndima Kongba, the military governor of North Kivu province said that seismic and ground deformation data indicates the presence of magma under the city, extending under Lake Kivu. He added that given the scientific observations, an eruption on land or under the lake cannot be ruled out at present, and it could occur with very little or no warning.<br />''<br />'' Chiara Frisone, a spokeswoman for the United Nations children's fund said that people are running to the west, to Sake, and east to Rwanda. She added that UN's emergency response teams and local partners were remaining in the city.<br />''<span style="color: #222222;"><br />''Thirty-one people were killed on Saturday when Mount Nyiragongo, one of the world's most active volcanoes, erupted.  The lava had stopped just 300 metres short of Goma airport, the main hub for aid operations in eastern Democratic Republic of Congo.</span><br />
