Hamas said on Thursday that U.S. President Trump's repeated threats against Palestinians constituted support for Israel's Prime Minister Benjamin Netanyahu to back out of the Gaza ceasefire and intensify the siege of Gazans.

Israel has introduced what it said was a new U.S. ceasefire plan and is trying to force Hamas to accept it by imposing a siege on the Gaza Strip

Hundreds of aid trucks have entered Gaza daily since the ceasefire began on Jan. 19​, and it was unclear what the immediate impact of the aid cutoff would be.

Israeli fire killed at least two people in Rafah and injured three others in Khan Younis in the south of Gaza, raising fear among Palestinians that the ceasefire could collapse altogether after Israel imposed a total blockade on the shattered enclave.

The announcement signaled a breakdown in the Israel-Hamas ceasefire deal, the first phase of which expired Saturday with no clear next steps.

A tense cease-fire between Israel and Hamas continued to hold amid a stalemate over an Israeli block on humanitarian aid going into Gaza after Hamas rejected a U.S. proposed extension.

The ceasefire in Gaza came closest to collapsing since it began in mid-January after Israeli Prime Minister Benjamin Netanyahu announced Israel’s halt of the entry of humanitarian aid into the strip.

Foreign Minister Gideon Saar said on Tuesday Israel was ready to proceed to the second phase of the Gaza ceasefire deal, as long as Hamas was ready to release more of the 59 hostages it is still holding.
