Hundreds of artists signed an open letter in which they asked for President Joe Biden and Congress to "call for an immediate de-escalation and ceasefire in Gaza and Israel before another life is lost."
"We believe all life is sacred, no matter faith or ethnicity and we condemn the killing of Palestinian and Israeli civilians," the letter reads, calling the loss of lives in both Israel and Gaza "devastating" and "catastrophic."
The current Israel-Hamas war began Oct. 7, 2023, when Hamas terrorists carried out a surprise attack on Israel, killing more than 1,200 people and taking more than 200 others hostage, according to Israeli authorities.
In response, Israel has carried out wide-scale counterattacks on the Gaza Strip over the past five months, killing more than 30,000 people and injuring more than 72,000 others -- many of them women, children and the elderly -- according to the Hamas-run Gaza Health Ministry.

The Gaza Strip is home to more than 2 million Palestinians who have lived under Hamas rule and an indefinite Israeli blockade since Hamas won legislative elections in 2007.
