As thousands of people who fled heavily bombed parts of Lebanon begin to return amid a tenuous peace deal with Israel, health workers are facing major challenges to restore services there, global health authorities have said.

Speaking to journalists on Thursday, Dr Tedros Adhanom Ghebreyesus, head of the World Health Organization (WHO), said Lebanon’s health needs are “huge” and “will only increase” in the coming months.

About 1.2 million people there were displaced by Israeli strikes and ground attacks that paused Wednesday morning (CET) after Israel and Lebanon agreed to a temporary ceasefire – though while many hoped it could signal the beginning of the end of the war, it’s not clear that peace will last after Israel accused Lebanese militant group Hezbollah of breaching the deal on Thursday.
