The Israel Defense Forces confirmed Tuesday that it has gained operational control of the Gazan side of the Rafah Crossing.

The IDF released a statement saying its forces began a "precise counterterrorism operation" in eastern Rafah.

Acting upon intelligence showing the area was being used for "terrorist purposes," IDF troops obtained operational control of the Gazan side of the Rafah Crossing, the statement said.

Intelligence gathered by the IDF and the Israel Securities Authority prompted the operation aimed at killing Hamas terrorists and dismantling "Hamas terrorist infrastructure within specific areas of eastern Rafah."

Before the operation, the IDF urged residents in eastern Rafah to temporarily evacuate to the expanded humanitarian area in Al-Mawasi, where the IDF facilitated the expansion of field hospitals and tents, and increased water, food and medical supplies. International organizations working in the area were also encouraged to temporarily evacuate before the operation began.

"Following intelligence that indicated that the Rafah Crossing in eastern Rafah was being used for terrorist purposes, IDF troops managed to establish operational control of the Gazan side of the crossing," the IDF said. "On Sunday, mortars were fired from the area of the Rafah Crossing toward the area of the Kerem Shalom Crossing."

Four IDF soldiers were killed during the operation and several others were injured after the mortars were fired.
