The director-General of the World Health Organization (WHO) says, Gaza is experiencing a health disaster that will last for generations to come.

Dr. Tedros Adhanom Ghebreyesus told news men  that a massive increase in aid is needed to begin to address the complex needs of the Strip’s population.

Israel has allowed more medical supplies and other aid to cross into Gaza since a ceasefire with Hamas came into effect on 10 October, but Dr Tedros said levels are below those needed to rebuild the territory’s healthcare system.

His intervention comes as the US attempts to shore up the ceasefire it helped to broker following an outbreak of violence at the weekend.

The agreement has been described by the White House as the first phase of a 20-point peace plan that includes an increase to the amount of aid entering Gaza, and supplies distributed “without interference” from either side.
