The United States said Tuesday the closure of border crossings into Gaza was "unacceptable," after “Israel” sent tanks into the southern city of Rafah and seized control of the crossing with Egypt – the US State Department said Tuesday.

"The crossings that have been closed need to be reopened, it is unacceptable for them to be closed," Press Secretary Karine Jean-Pierre told a briefing, adding that another crossing, at Kerem Shalom, was expected to reopen Wednesday.
