Palestinian gunmen in Gaza have fired at a car carrying the director of the UN refugee relief agency Irishman John Ging.
Mr Ging, who is the director in Gaza of the UN Relief and Works Agency (UNRWA), was travelling from the Erez border when his armoured car was hit five times by gunfire from a passing vehicle.
"There is no information on who did the shooting," an UNRWA official in Gaza said. Palestinian attacks on UNRWA - which supplies vital aid and employment for refugees in Gaza, the occupied West Bank and neighbouring Arab countries - have been very rare.
In a separate incident, gunmen shot dead an intelligence officer loyal to Palestinian President Mahmoud Abbas also in Gaza, a day after rival factions agreed on the make-up of a unity government.
No group immediately claimed responsibility for the attack on a car in the central Gaza town of Deir al-Balah in which Hussein Asserhi was killed and a passenger was wounded.
Palestinians hope the unity deal will end street fighting between Mr Abbas's secular Fatah group and Islamist Hamas that has claimed more than 300 Palestinian lives in the past year.
Mr Abbas and Prime Minister Ismail Haniyeh of Hamas agreed to form a coalition government during Saudi-sponsored talks in Mecca on February 8th after violence sparked fears of civil war.
Disagreement over who would control Palestinian security forces was a major obstacle in coalition talks, but Mr Abbas and Mr Haniyeh agreed to appoint an academic with no security experience to the hotly-contested post of interior minister. The unity government is also aimed at easing a crippling Western aid embargo of the Palestinian Authority.
