Peace activists sailing towards the Gaza Strip to break a suffocating siege have lost contact with the world amid Israeli threats.
As the two boats carrying 46 activists from 14 countries neared the area, their electronic systems were jammed and scrambled and they are unable to use their electronic navigation instruments and transmit distress messages.
According to the group's website, freeGaza.org, "all electronic systems aboard the SS Free Gaza and SS Liberty have been jammed and scrambled."
We are currently relying on our satellite communications equipment to make a distress call, if needed, the Free Gaza Movement said in a statement.
"This interference runs contrary to international shipping rules and safe navigation rules," said Syriza, one of whose parliamentary deputies, Tassos Kourakis, is among the activists.
This is while PressTv's attempts to communicate with its journalist, Yvonne Ridley have been unsuccessful.
Israel jammed their communications following its threats against the activists.
Israeli officials said on Saturday that Israel was closely following the boats and "all the options are being considered.''
