Israeli occupation navy on Wednesday intercepted an activist boat seeking to break the country's decade-long blockade of the Gaza Strip, saying it was boarded without incident and was being directed to shore.
The navy said in a statement that its forces had "redirected" the sailboat in order to prevent a "breach of the lawful maritime blockade" of the Palestinian enclave.
It said this was done "in accordance with government directives and after exhausting all diplomatic channels".
Thirteen women, including 1976 Nobel Peace Prize winner Mairead Maguire, had been travelling aboard the Zaytouna-Oliva sailboat in the Mediterranean toward Gaza, run by Islamist movement Hamas.
The Zaytouna-Oliva set sail from Barcelona in September and was carrying women of various nationalities in addition to Maguire, a Northern Ireland activist.
Dubbed "Women's Boat to Gaza", it is part of the wider Freedom Flotilla Coalition that consists of pro-Palestinian boats that regularly seek to go to Gaza to try to break the blockade.
One such operation turned to tragedy in 2010 when Israeli commandos killed 10 Turkish activists in a raid on a flotilla.
In Wednesday's operation, the Israeli occupation navy said it intercepted the sailboat after advising it "numerous times to change course prior to the action".
It said its forces had boarded and searched the sailboat, describing the operation as "uneventful".
The sailboat was now believed to be headed toward the Israeli port of Ashdod. Organisers said they had lost communication with the activists.
It was boarded around 35 nautical miles from the coast, Israeli public radio reported, citing a navy officer.
"Following their refusal, the navy visited and searched the vessel in international waters in order to prevent their intended breach of the lawful maritime blockade of the Gaza Strip."
Hamas denounced the move as "state terrorism".
Israel has launched three devastating wars on Gaza since 2008.
Israel maintains a blockade to keep material it claims could be used for military purposes from entering the impoverished enclave of 1.9 million people.
UN officials have called for the blockade to be lifted, saying conditions are deteriorating in Gaza.
Earlier on Wednesday, Israel occupation military struck several Hamas positions in the Gaza Strip after a rocket launched from the Palestinian enclave hit the nearby Israeli city of Sderot, with no casualties reported on either side.
Israel holds Hamas responsible for all such rocket fire and often responds with air and tank strikes, but recent responses have been stronger than in the past.
That has led some analysts to question whether the change is the result of a new policy by hardline Defence Minister Avigdor Lieberman, who took office in May.
In August, Israel occupation forces carried out dozens of retaliatory strikes after a rocket hit Sderot, a far larger response than usual.
Israeli media reported that attack was the first time downtown Sderot had been struck by a rocket from Gaza since the last war in 2014.
The 2014 assault was the most devastating of the three, killing 2,251 Palestinians and leaving 100,000 homeless.
Seventy-three Israelis died in the offensive.
A delegation from the International Criminal Court is visiting Israel and the Palestinian territories this week, its chief prosecutor said Wednesday, against the backdrop of a probe into the last Gaza war.
