Where does the Israel-Hamas ceasefire stand now? Here's a timeline on the latest developments

The first phase of a fragile ceasefire agreement between Israel and Hamas in Gaza crumbled earlier this week after Israel pounded the enclave with heavy airstrikes — the deadliest since the truce was signed. 

The latest violence has left at least 600 Palestinians dead so far this week, many of whom were women and children. UNICEF says Tuesday's attack was the largest single-day death toll of children in the last year. 

But the assault wasn't the first violation of the ceasefire over the last two months.

Israel has warned that Tuesday's strikes were "just the beginning," launching a ground invasion into central and southern Gaza on Wednesday and expanding into north of the enclave Thursday. 

While Israel has not formally declared an end to the January ceasefire agreement with Hamas, Tuesday marked a turning point in the region, threatening to renew full-scale warfare.

Here's a timeline of key dates since the ceasefire deal was signed:

Negotiators reach a deal for a ceasefire between Israel and Hamas after 15 months of conflict.

The three-phased deal includes hostage and prisoner releases while delaying talks on Gaza's future to a next stage of the truce.

Hamas frees a first batch of hostages as Phase 1 of the ceasefire agreement — a 42-day period — comes into effect. 

Israel also releases a first batch of Palestinian detainees in the following hours.

After only a couple weeks in office, U.S. President Donald Trump declares his intent for the United States to take ownership of the Gaza Strip and turn it into the "Riviera of the Middle East," as the Israel-Hamas ceasefire continues to hold.

Hamas threatens to stop hostage releases, accusing Israel of failing to respect stipulations in the agreement surrounding aid deliveries, but later says they will be released as scheduled.

Israel also accuses Hamas of breaching the agreement, saying Hamas had fired a rocket from Gaza that landed in the enclave. Hamas denies the allegations, saying it was an unexploded Israeli ordinance that had ignited and fired into the air while it was being moved away from a residential area.

The first phase of ceasefire expires without agreement on a second phase. Israel says first phase should be extended with further hostage releases. Hamas says original deal should be continued, with second-phase talks.
