Jordanian security forces late Saturday arrested an Iraqi suspect over the rocket attacks targeting US warships docked in Jordan's Red Sea port of Aqaba and neighboring Israel's Eilat on Friday, said a security source.
"Security forces arrested the Iraqi suspect while he was driving his car," said the source on condition of anonymity, without giving further details.
Earlier, Jordanian security agencies said it started a manhunt for four suspected Arab nationals, including the Iraqi.
Rocket blasts hit Jordan's Aqaba port and Israeli city Eilat on Friday morning, the al-Jazeera TV channel reported.
A Jordanian official statement confirmed later that three Katyushas were fired from the roof of a warehouse in Aqaba port, killing one Jordanian soldier and wounding another.
One rocket hit a Jordanian armed forces depot, the second landed near a military hospital, while the third fell on the Israeli port city of Eilat, the statement added.
