The official Twitter account of the Israel Defense Forces was compromised Thursday afternoon and used to send out a pro-Palestinian message and warn of a possible nuclear disaster.

“Long live #Palestine,” one of the messages read.

Another message warned of a “possible nuclear leak in the region.”

The tweets were quickly removed and an apology was sent out from the IDF, acknowledging their account had been compromised.

The apparent hack appeared to be the work of the infamous Syrian Electronic Army, which has targeted several high profile individuals, groups and businesses in the past. In October, the group appeared to hack a page on President Barack Obama’s presidential campaign website.
