The following official press release from Kevin Ovenden, convoy leader for Viva Palestina, was provided at 8pm.
'To all friends of Palestine
Our situation is now at a crisis point! Riot has broken out in the port of Al- Arish.
This late afternoon we were negotiating with a senior official from Cairo who left negotiations some two hours ago and did not return. Our negotiations with the official was regarding taking our aid vehicles into Gaza.
He left two hours ago and did not come back. Egyptian authorities called over 2,000 riot police who then moved towards our camp at the port.
We have now blocked the entrance to the port and we are now faced with riot police and water cannons and are determined to defend our vehicles and aid.
The Egyptian authorities have by their stubbornness and hostility towards the convoy, brought us to a crisis point.
We are now calling upon all friends of Palestine to mount protests in person where possible, but by any means available to Egyptian representatives, consulates and Embassy’s and demand that the convoy are allowed a safe passage into Gaza tomorrow!'
