(CNN) -- An Israeli patrol boat struck a boat carrying medical volunteers and supplies to Gaza early Tuesday as it attempted to intercept the vessel in the Mediterranean Sea, witnesses and Israeli officials said.

CNN Correspondent Karl Penhaul was aboard the 60-foot, Gibraltar-registered pleasure boat Dignity when the contact occurred. When the boat later docked in the Lebanese port city of Tyre, severe damage was visible to the forward port side of the boat, and the front left window and part of the roof had collapsed.

The Dignity was carrying 16 passengers and crew who were trying to reach Gaza through an Israeli blockade of the territory.

The captain of the Dignity said the Israelis broadcast a radio message accusing the vessel of being involved in terrorist activity. But Israeli Foreign Ministry spokesman Yigal Palmor denied that and said the radio message simply warned the vessel not to proceed to Gaza because it is a closed military area.

Palmor said there was no response to the radio message, and the vessel then tried to out-maneuver the Israeli patrol boat, leading to the collision.

Penhaul said at least two Israeli patrol boats had shadowed the Dignity for about half an hour before the collision, moving around the vessel on all sides. One of the patrol boats then shined its spotlight on the Dignity while the other, with its lights off, "very severely rammed" the boat.
