UPDATE 2-Red Cross attacked with rockets, grenades in Libya

(Adds Libyan spokesman's reaction and background paras 5-7)

GENEVA, Aug 5 (Reuters) - Unknown assailants attacked a

compound of the International Committee of the Red Cross in the

Libyan port of Misrata on Sunday with grenades and rockets,

forcing it to suspend its work there and in the eastern city of

Benghazi, the agency said.

The ICRC said seven of its aid workers were inside their

residence when it came under attack. No one was hurt, but damage

to the building was extensive.

It was the fifth time in less than three months that

violence was directed against the independent aid agency in

Libya, the ICRC said in a statement, which stressed its

neutrality.

"Given the circumstances, we are forced to announce, with

considerable regret, that we will be suspending all our

activities in Misrata and Benghazi and that our delegates in

those cities will be temporarily relocated," said Ishfaq Muhamed

Khan, the head of the ICRC's delegation in Libya.

Several violent incidents have rocked Libya in recent days

and included the kidnapping on Tuesday in Benghazi of seven

Iranians relief workers who were official guests of the Libyan

Red Crescent Association.

Also on Sunday, security forces killed three armed men who

were suspected of being behind seven failed bomb plots, said

Saleh Darhoub, a spokesman for the National Transitional

Council. It was the first deadly clash since the fall of Muammar

Gaddafi in October.

Darhoub promised to bring the attackers to court and

condemned their act against what he described as "hosts" of

Libyans "who did great things for the revolution including in

Misrata".

In Geneva, ICRC spokesman Jean-Yves Clemenzo said that the

seven staff had withdrawn to its delegation in the capital

Tripoli. "We do not know who carried out the attack. Grenades

and RPGs (rocket-propelled grenades) were used, it was a serious

incident," he told Reuters.

The ICRC has a humanitarian mandate to protect people

affected by armed conflict and other situations of violence and

to provide them with assistance, it said.

"The ICRC is not involved in political or religious

activities of any kind, neither in Libya nor anywhere else," it

added. Clemenzo said that the organisation was sometimes

mistaken for a religious movement, which is not the case.

Throughout the revolt last year that ousted Libyan leader

Muammar Gaddafi, ICRC aid workers delivered food and medical

assistance to civilians, including those trapped in Misrata,

which was long held by rebels under siege by Gaddafi's troops.

"We are appalled by this latest act and by the deliberate

targeting of our staff: they have put their lives at risk to

serve the Libyan people both during and after the conflict,"

Khan said.
