"Gaza is now forgotten," the Vicar General Patriarchate of Jerusalem has said as he visits Ireland to highlight issues facing Palestinians in the enclave and the West Bank.
Catholic Bishop William Shomali called for further Irish advocacy on the conflict.
Speaking on RTÉ's Morning Ireland, he said: "Every day there are strikes and people are still afraid. It is difficult to move out and into Gaza.
"The Rafah passage is limited in its capacity to allow people in and out.
"Many people are poor, not working and are hungry. Many medicines are not there," he said.
Bishop Shomali also said that the Board of Peace created by US President Donald Trump has "not been active".
He said that in the last two years, Israeli settlers have become "stronger" in the West Bank and want to expand their settlements.
Bishop Shomali said settlers are preventing Palestinians from harvesting on their own land.
"This renders difficult the life of Palestinians, among them, many Christians," he added.
Bishop Shomali said Christians in the region are living in a difficult situation and unemployed young people are considering leaving.
"We have had many crises in the past, but this one is the most difficult they have ever lived," he added.
Israeli attacks kill eight people in Gaza, medics say
He was speaking after Israeli strikes killed at least eight Palestinians in Gaza yesterday, health officials said.
In the weeks since halting its joint bombing with the US in Iran, Israel has stepped up its attacks in Gaza, where Hamas has been tightening its grip, even as Israeli troops remain in control of more than half the territory.
Medics said an Israeli strike killed one Palestinian near a police post and another at a tent encampment in Khan Younis in southern Gaza.
The Israeli military said it killed a militant who posed an immediate threat to forces in the area.
Separately, Gaza medics said another Israeli airstrike killed at least three people at a community kitchen near Al-Aqsa Hospital in Deir al-Balah, in the central Gaza area.
The Israeli military said the strike targeted a Hamas commander developing anti-tank missiles.
Gaza medical officials said three more Palestinians were killed, one in a shooting incident in Khan Younis in southern Gaza and two others in an Israeli airstrike near a bakery in Deir al-Balah in central Gaza.
On Saturday, the Israeli military said Izz al-Din al-Haddad, the head of Hamas' armed wing in Gaza, was killed in what it described as a precise strike on Gaza City on Friday.
Hamas confirmed Mr Haddad's death but stopped short of threatening revenge.
The Israeli military said it had also killed Bahaa Baroud, a Hamas Operations Headquarters commander, in an airstrike on Saturday, accusing him of planning multiple imminent attacks against troops and Israeli civilians in recent weeks.
The military said Mr Baroud posed an immediate threat and was targeted in a precise strike, adding that measures were taken beforehand to reduce civilian harm, including the use of precision munitions and aerial surveillance.
Gaza health officials said Mr Baroud, along with another person, was killed in the airstrike, which targeted their car in Gaza City.
Israel and Hamas remain deadlocked in indirect talks to advance President Donald Trump's post-war plan for Gaza that is meant to end more than two years of fighting with Hamas disarming as Israeli troops withdraw from Gaza.
Some 870 Palestinians have been killed in Israeli attacks since the October ceasefire.
Four Israeli soldiers were killed during the same period.
More than 2 million people now live in a tiny strip of territory along the coast in Gaza, mainly in damaged structures or makeshift tents, as a result of Israel's continued attacks.
Israeli attacks have killed more than 70,000 people in Gaza since October 2023, according to figures from Gaza authorities, deemed reliable by the UN.
Hamas' 7 October 2023 attack on Israeli killed over 1,200 people, according to Israeli tallies.
