The Jordanian Royal Navy arrested an Israeli who entered Jordanian waters on Saturday, the navy announced on Sunday.
The detainee had been attempting to swim across into Jordan via the Gulf of Eilat.
The IDF later confirmed that a report had been received on Saturday of an Israeli civilian who crossed by sea from Israeli territory into Jordanian waters and was subsequently detained by Jordanian forces.
"Israeli security authorities have been working through the relevant channels to ensure his safe return," the IDF added.
According to Ma'ariv, the detainee, a man in his late 50s, crossed the maritime border by mistake while paddleboarding. He is believed to have been carried over the border by the wind before Israeli Navy vessels could reach him.
Israeli media reported on Sunday evening that Jordanian authorities had released the Israeli detainee.
Security forces seize pistols, drugs near Jordan border
Elsewhere along the Jordanian border over the weekend, Israeli security forces seized eight pistols, a large quantity of a substance suspected to be hashish, GPS devices, and SIM cards in two separate incidents, in a joint operation by the police, the IDF, and the Border Police.
Investigators are now trying to determine who was behind the suspected smuggling attempts and where the weapons and drugs were headed.
In the first incident, IDF surveillance soldiers spotted suspicious movement along Israel’s eastern border with Jordan. Officers from the police’s Jordan Border Unit, part of the Judea and Samaria (West Bank) District, were called to the scene, along with soldiers from the IDF’s 47th Battalion and a Border Police unit.
Searching the area, the forces found a sack hidden in the field containing eight FN, Glock, and Taurus pistols, which police suspect were meant to be smuggled into Israel. The weapons were sent to forensic investigators in an effort to identify those involved.
In a second incident over the weekend, forces searching the border area found another sack containing a large quantity of a substance suspected to be hashish, along with GPS devices and SIM cards. These were also sent for forensic examination.
No arrests have been reported in either of the weekend’s incidents. The investigation is ongoing, and the police, the IDF, and the Border Police are continuing to operate along the border to thwart further smuggling.
