The rescue comes well after the initial three-day period immediately after the quake during which experts say people trapped under debris have the best chance of being found alive.

La Guaira is one of the hardest hit areas, with many local people trying to carry out rescue efforts themselves.

The UN’s refugee agency said on Tuesday that food shortages were widespread, basic services had broken down and communications had been largely severed in La Guaira.

“Community tensions are rising as access to assistance remains constrained,” the UNHCR said in a statement on its website.

Daniela Armas, an 18-year-old vendor in La Guaira who was injured falling from a motorbike when the quakes struck, told AFP that some supplies were being distributed “but sometimes people nearly kill each other for food… it’s like a cockfight.”

The UNHCR said that it needed an initial $15m to “scale up protection, core relief items, and temporary shelter support for 30,000 earthquake-affected people over six months”.

Meanwhile the World Health Organization (WHO) said health services were under “extreme pressure.”

“There’s an increased risk now of outbreaks of vaccine-preventable diseases” such as measles and diphtheria due to low vaccination coverage, WHO spokesman Christian Lindmeier said.
