Israel says its soldiers boarded the Irish-owned Rachel Corrie from the sea and did not meet any resistance.

There has been no word from those on board, among whom are several activists.

The incident comes five days after nine people were killed in clashes when troops boarded a Turkish aid ship, prompting international criticism.

Turkish officials have released details of autopsies carried out on the nine dead activists, saying a total of 30 bullets had been found in their bodies.

One of the activists was shot four times in the head, the officials said.
