More than 200 people have been killed in Gaza since the ceasefire between Israel and Hamas went into effect on Oct. 10, Doctors Without Borders said on Thursday, citing the Hamas-run Gaza Ministry of Health.

At least 104 people were killed after Israel resumed strikes on Gaza in a brief break in the ceasefire earlier this week, according to the Ministry of Health. At least 253 people were injured, the ministry said.

"We need a sustained ceasefire to stop the overwhelming level of death and catastrophic injuries suffered by civilians," Doctors Without Borders Senior Communications Officer Brienne Prusak said in a statement Thursday.

Israeli forces are now in possession of two coffins transferred to them from the Red Cross, the Israeli prime minister’s office said in a release Thursday.

The coffins will be taken to Israel and will be examined by the Israeli Ministry of Health’s National Center for Forensic Medicine for identification, it noted.

Israeli forces struck 30 "terrorist targets" in Gaza from Tuesday into Wednesday before announcing the ceasefire was back in effect, the Israel Defense Forces said in a statement.

The IDF conducted strikes in Khan Younis and in northern Gaza, it noted in separate statements.

At least 91 Palestinians were killed in these strikes across Gaza, according to Gaza Civil Defense.

The IDF also announced that one of its reservist soldiers was killed in an attack in Rafah on Tuesday. Israel cited the killing as one of the reasons why it conducted strikes on Gaza on Tuesday and Wednesday. Hamas denied involvement with the killing of the soldier.

The Israel Defense Forces said in a Wednesday morning statement that it had resumed adherence to the ceasefire in Gaza "following a series of significant strikes in which dozens of terror targets and terrorists were attacked."

"The IDF will continue to enforce the agreement and respond forcefully to any violation," the statement said.

The Hamas-run Civil Defence agency said that at least 91 Palestinians were killed in the renewed strikes across Gaza.

The bombardment came after one Israeli soldier was killed in an attack in the southern Gaza city of Rafah on Tuesday. Hamas denied involvement in the incident.
