Tripoli, Libya (CNN) -- Despite coalition airstrikes, troops loyal to Libyan leader Moammar Gadhafi continued to terrorize residents of the besieged rebel-held city of Misrata Wednesday.
In the city's main hospital, where 400 people -- about half of them patients -- were located, one witness said Gadhafi's forces had attacked. The push began at 8 p.m. (2 p.m. ET), when "heavy tanks for Gadhafi troops start attacking the hospital -- the bombs falling here 20 meters (66 feet) around us," said one person inside the hospital. He said two deaths had occurred "around the hospital."
At one point, shelling occurred without respite for 40 minutes, he said. "Now, fortunately, no more shelling, but the situation is so serious that all the teams here -- the doctors, the patients -- are paralyzed, scared."
He called for international intervention to protect the civilians inside the institution. "Nobody can work here," he said. All the doctors here are completely paralyzed." Ambulances were not able to leave the hospital, which had lost its electricity and was running on generator power, he said.
During the last day, the international coalition has flown 175 sorties over Libya -- 113 of them by U.S. planes and the remainder from other nations participating in the U.N.-backed mission, U.S. Navy Rear Adm. Gerard Hueber told reporters Wednesday.
crippled, and the no-fly zone spans Libya from east to west along its coastline, said Hueber, the chief of staff for U.S. operations. But the coalition has had no indication that Gadhafi was complying with a United Nations mandate to stop attacks against civilians.
With Gadhafi's air power rendered ineffective, coalition airstrikes were focusing on his ground forces in Ajdabiya and Misrata.
Coalition jets are using smart bombs to target mechanized forces and mobile surface-to-air missile sites and impede supply lines for their "beans and bullets," Hueber said. The targets include Libya's premier 32nd Brigade, commanded by one of Gadhafi's sons and fully engaged in the fighting.
"It's an extremely complex and difficult environment," Hueber said about going after forces in populated areas.
"And our primary focus is to interdict those forces before they enter the city ... cut off their lines of communication and cut off their command and control," he said. "There have been no reports of civilian casualties. Our mission here is to protect the civilian populace and we choose our targets and plan our actions with that as our top priority."
Wednesday night's outbreak of violence broke a respite that began earlier in the day with the coalition attacks -- the first calm in a week, Misrata residents reported.
"We would like to express our gratitude to the international community since there were airstrikes this morning," said Mohammed, an opposition spokesman in the city who would identify himself only by his first name.
Gadhafi's forces had been stationed on the outskirts of the city, where they were providing support and supplies to loyalists fighting rebels in Misrata proper.
Earlier in the day, grocery stores and other shops opened in the city, which is located two hours east of Tripoli and has been inaccessible to journalists.
One person inside the hospital told CNN that five more people were killed in the last 24 hours, raising the death toll to at least 95 in the last seven days. A man who died Wednesday morning was shot by a sniper, the doctor said.
Gen. Abdul Fatah Younis, a former interior minister who quit to lead opposition forces, said rebels have requested weapons from several nations to help the embattled city.
"Misrata is destroyed and they need weapons," Younis told CNN. "We try to send them weapons, but of course they were all light weapons. There were no heavy weapons."
In Tripoli, the clatter of anti-aircraft weapons could be heard.
In Ajdabiya, parts of the city fell to opposition forces even though Gadhafi's men, who have been pounding the area with artillery and heavy tank bombardments, retained control of the northern and western gates, opposition fighters and witnesses told CNN.
A hospital staffer and opposition fighters said nine people were killed Wednesday in fighting near the northern gate.
The international airstrikes against Libyan military positions began over the weekend after Gadhafi defied a United Nations-mandated cease-fire in attacks against civilians. The strikes are intended to help establish a no-fly zone.
The campaign was in its fifth day as Sweden announced it has frozen more than $1.53 billion in Libyan assets in response to EU sanctions imposed on the northern African country.
France launched the air campaign in Libya and Britain and the United States followed. Germany is not participating in the military action, though it agrees with the United Nations resolution in principle, and moved Wednesday to ensure that its ships were far removed from the Libyan campaign.
A German navy spokesman said Wednesday that all German ships previously under NATO command in the Mediterranean Sea were reassigned to operate under national command and are returning to previously scheduled port stops in Europe to await further instructions. German crew members of NATO fighter jets were also under German command.
Britain announced an international meeting for next Tuesday called to assess successes and needs in Libya.
Late Monday, coalition forces suffered a setback when a U.S. fighter jet malfunctioned and crashed near Benghazi in eastern Libya.
The two crew members parachuted out and landed in different places. U.S. rescue teams, picking up the pilot, dropped two 500-pound laser-guided bombs after they saw an armored vehicle approaching the pilot and feared for his safety, said Capt. Richard Ulsh, spokesman for the 26th Marine Expeditionary Unit.
An investigation of the incident is underway after reports surfaced that some Libyans were wounded by shrapnel.
Capt. Becky Massey, the pilot of one of the two Osprey tilt-rotor aircraft involved in the rescue, said the bombs were dropped three miles from the downed pilot. One of the Ospreys then landed and picked up the pilot.
A U.S. aircraft later dropped munitions on the F-15E wreckage to destroy it, a U.S. military official told CNN.
Rebels had already recovered the second crew member, a weapons officer, and treated him with "respect and dignity" until coalition forces reached him, U.S. Navy Adm. Samuel Locklear III said Tuesday. It was not immediately clear how the weapons officer was retrieved by U.S. authorities.
The Libyan war was sparked in February by protests demanding an end to Gadhafi's almost 42-year rule. The Libyan strongman responded with force, prompting the international community to take action.
However, a Johns Hopkins University professor said the coalition can achieve only so much through aerial strikes.
"We have to understand the limits of what air power can do," Fouad Ajami told CNN's "AC360."
"This is a recipe for a stalemate," he said.
Criticism and questions persist about the international campaign, with no clear answer on who will take over command of the mission and what the exit strategy will be.
U.S. President Barack Obama said the timetable for a transition of military leadership will be coming in days, not weeks.
NATO said Wednesday it will decide shortly what its role in the operation will be. A spokesman added the alliance is well prepared.
"This is the bread and butter of NATO," an official said.
French Foreign Minister Alain Juppe has voiced his opposition to NATO taking political leadership over the Libya campaign. He suggested that a commission composed of foreign ministers from the participating states play that role.
Ajami, however, said the Arab world would welcome NATO involvement.
"They know that the calamity is unfolding in Libya, and they know that no help is going to come other than from the West and from the United States."
British Prime Minister David Cameron said Wednesday that Kuwait and Jordan have agreed to provide logistical support to the Libyan effort.
Jordanian government spokesman Taher Edwan told CNN that Jordan's role will be limited to a humanitarian one. "Jordan did not and will not have any military participation in Libya, neither in planes or on the ground at all in Libya," he said.
Qatar has already contributed planes to mission.
The United Arab Emirates said Tuesday it will participate -- but only in providing humanitarian assistance.
Toward that end, the country has sent a ship and two planes with basic relief supplies, the country's news agency said.
