GENEVA/PORT-AU-PRINCE (AFP/Reuters) - Violence and looting are on the rise in Haitis capital as aid only trickles through to victims six days after the country was shattered by a huge earthquake, the International Committee of the Red Cross said Monday. Prices for food and transport have skyrocketed since last Tuesday and incidents of violence and looting are on the rise as the desperation grows, the ICRC said in a statement. Many residents of Port-au-Prince felt they were in a catastrophic situation, it added. Access to shelter, sanitation, water, food and medical care remains extremely limited, said Riccardo Conti, the ICRCs head of delegation in Haiti. UN and Red Cross agencies said earlier that the relief effort was finally gaining pace on Monday as field hospitals and food distribution started to fall into place and the stuttering international aid effort expanded. Even if the presence of aid agencies is starting to be felt in hospitals and clinics, many medical facilities in Port-au-Prince still lack staff and medicine, said Conti. Given the scale of the needs, the task facing humanitarian organizations is daunting, he added. The ICRC said that nearly a week after the magnitude 7.0 quake struck, the health and sanitation situation was growing increasingly precarious in makeshift camps. With vast numbers of people sleeping in the streets, the availability of toilets and fresh water was extremely limited, while all over Port-au-Prince the stench of urine is overpowering. We must rapidly address these water and sanitation issues if we want to minimize the risk of an outbreak of disease, said Conti. This is really paramount. ICRC water trucks were supplying about 7,500 people in three makeshift camps while latrines for around 1,000 people were built in the eastern Delmas neighbourhood. Elisabeth Byrs, a spokeswoman for the UN Organisation for the Coordination of Humanitarian Affairs, admitted the population was on edge but said looting was within proportions expected in such a disaster, with half the police force out of action. The situation is still tense but calm, she told AFP. We are accelerating the pace, we are fanning out on the ground, but the needs are enormous, enormous. Byrs also appealed to Haitians in the southern quake zone to free the roads to allow aid through. Relief workers, she added, were sleeping in the open or in cars. Looters roamed the ruins of downtown Port-au-Prince virtually unchallenged Monday, plucking anything of value from collapsed buildings and shrugging off the occasional crack of gunfire. A dozen masked men swarmed over a rare prize a quake-smashed clothing store still stuffed with goods and pulled out colorful bolts of cloth from openings in the rubble. Three private guards hired to protect the store looked on, pointing pump action shot guns in the direction of the thieves who went on working unfazed. An AFP reporter saw no police, or rescue workers, and none of the American soldiers based on the outskirts of the city visible in the citys center, the heavily damaged heart of its business and government district. A United Nations human rights panel on Monday called for immediate measures to protect thousands of children believed to have been orphaned or separated from their parents in Haitis earthquake. Children are always deeply affected by major disasters of this type, and almost half of the Haitian population are children, the UN Committee on the Rights of the Child said in a statement. The panel said it was alarmed by emerging reports of looting and violence, which highlight the importance of immediately adopting effective systems and measures to protect children from all forms of violence and exploitation, including sexual abuse and abductions masquerading as adoptions. The 18 legal experts, who are currently meeting in Geneva, said they were particularly concerned for those who were isolated from their families following last weeks quake. Haitis quake-ravaged capital looks like it was hit by a nuclear blast, US Ambassador Ken Merten said Monday. Port-au-Prince looks like Tokyo probably did after World War II. Its flat. It looks like an atomic bomb went off, Merten told CNN. Forty-six UN personnel are now confirmed dead in the Haiti quake and more than 500 are missing or unaccounted for, UN spokesman Martin Nesirky said Monday. Some 70,000 bodies have been buried in mass graves in Haiti and a state of emergency has been declared until the end of January, a Haitian minister said Sunday. There would also be a month-long period of national mourning, the minister Carol Joseph said. Aid agencies said a huge international relief operation nearly a week after Haitis devastating earthquake was gaining pace on Monday, but one warned that survivors were growing increasingly desperate. UN agencies and the Red Cross said field hospitals and food distribution had multiplied in and around the capital Port-au-Prince. The United States was to send more troops on Monday to aid in Haitis rescue as tens of thousands of hungry, thirsty and injured Haitian earthquake survivors waited desperately for promised food and medical care. The US Southern Command said some 2,200 Marines with heavy equipment to clear debris, medical aid and helicopters, would join some 5,000 US troops already in the region. The aim is to have approximately 10,000 US troops in the area to participate in the rescue operation, spokesman Jose Ruiz of the US Southern Command said. The OCHA said hospitals on the Dominican Republics border with Haiti were overwhelmed with quake victims, who had fled in recent days to seek treatment while international relief workers struggled with transport bottlenecks and the lack of local resources. The UN-led aid effort was broadening to thousands more people in severely battered outlying communities in the south of Haiti. The overall aim is to cover the needs for 200,000 families (one million people) within the next few weeks, OCHA said in its daily situation report. About 105,000 one-week food rations have been distributed since the emergency relief operation began last week, with 95,000 more due to be handed out on Monday by aid workers and UN peacekeeping troops, the UN World Food Programme said. The OCHA and the Red Cross said more field hospitals were in operation, carrying out long delayed emergency surgery on victims of crush injuries, while two mobile health units and water specialists fanned out in the quake zone. They included a Norwegian and Canadian Red Cross field hospital outside the University Hospital in the centre of the capital, which was severely damaged in the quake last Tuesday. Meanwhile, the fuel situation in Haiti is becoming more and more critical, OCHA said, warning that a shortage could have a serious impact on relief. The national telecommunications system has been partly restored, but without access to fuel the mobile network will be cut off within days, which will have serious implications for the humanitarian operation, OCHA added. Some 10,000 gallons (40,000 litres) of fuel are to be ferried in by truck daily on congested roads from the Dominican Republic. The International Organisation for Migration said it was planning with Haitian authorities to resettle 100,000 people, possibly in an area about 13 kilometres (eight miles) northeast of Port-au-Prince. Like the tsunami, the response will be on a huge scale and last for months, said Byrs, referring to the December 2005 disaster in Asia. Search and rescue teams from the United States pulled a record 10 people alive from the rubble of quake-struck Port-au-Prince on Sunday, the US Agency for International Aid said Monday. European Union nations earmarked on Monday sums approaching half a billion euros in emergency aid and reconstruction funds to help rebuild quake-ravaged Haiti. At emergency talks in Brussels, EU development ministers decided that the European Commission and EU nations will donate 122 million euros in emergency humanitarian aid, senior officials told reporters.
