Protesters blocked troops en route to Gaza on Friday, calling on the Israeli government to allow the flotilla into the enclave.
Soldiers and police forcibly removed them, clearing the way for troops and military vehicles to pass.
Protester Ella Greenderg Kedear expressed solidarity with the flotilla.
"My full solidarity is with the Sumud flotilla and the arrestees right now in the occupation prisons," she said.
She hoped that they would stay strong and that eventually the Israeli siege will be broken.
Israeli forces intercepted on Friday the last boat from an international flotilla trying to break Israel's sea blockade of war-ravaged Gaza as cities around the world erupted into more protests against Israeli actions in Gaza and the arrests of some 450 activists who were on the boats.
The interceptions of the flotilla boats and the arrest of the activists sparked demonstrations across continents, from Latin America to Asia.
Israel’s campaign in Gaza has killed more than 66,200 Palestinians and wounded nearly 170,000 others, according to Gaza’s Health Ministry.
The ministry does not differentiate between civilians and militants in its toll, but has said women and children make up around half the dead.
The ministry is part of the Hamas-run government. U.N. agencies and many independent experts view its figures as the most reliable estimate of wartime casualties.
Around 400,000 Palestinians have fled famine-stricken Gaza City since Israel launched a major offensive there last month.
The Hamas-led attack on southern Israel on Oct. 7, 2023 that triggered the war killed some 1,200 people while 251 others were abducted. Most of the hostages have been freed under previous ceasefire deals.
