BEIRUT — Warnings from Syrian activists of a humanitarian catastrophe in Homs grew more desperate Thursday as government forces resumed shelling an opposition stronghold in the restive central city, where hundreds have died in a weekslong siege.

About 30 people, including two Western journalists, were killed in shelling on Wednesday — most of them in the rebel-held Baba Amr neighborhood, which is the center of the resistance in the city. Homs has been under a fierce government attack for nearly three weeks.

Homs-based activist Omar Shaker said intense barrages hit residential districts in Baba Amr again Thursday, but there was no immediate word on casualties. He said food, water and medical supplies are running dangerously low in Baba Amr.

“Every minute counts. People will soon start to collapse from lack of sleep and shortages in food,” he said.

On Wednesday, shelling of Baba Amr killed American-born veteran war correspondent Marie Colvin and French photographer Remi Ochlik.

They were among a group of journalists who had crossed into Syria illegally and were sharing accommodations with activists, raising speculation that government forces targeted the makeshift media center where they were staying. But opposition groups previously described the shelling as indiscriminate. At least two other Western journalists were wounded on Wednesday.

A Syrian Foreign Ministry spokesman offered condolences to the families of Ms. Colvin and Mr. Ochlik but rejected any responsibility for their deaths. The spokesman urged foreign journalists to respect Syrian laws and not to sneak into the country.

Some Syrians held protests and vigils Wednesday night in several parts of Homs in commemoration of Ms. Colvin and Mr. Ochlik.

“Remi Ochlik, Marie Colvin, we will not forget you,” read one banner held by protesters in the town of Qsour in Homs province.

In the northwestern city of Aleppo, security forces fired tear gas at hundreds of students at Aleppo University staging an anti-regime protest. Aleppo, like the capital, Damascus, has remained relatively quiet during the nearly yearlong anti-government uprising gripping the country. But the city has become increasingly tense, particularly the university, where authorities fired on protesting students on Wednesday and killed one.

In Geneva, a panel of U.N. human rights experts said Thursday that the United Nations has a secret list of top Syrian officials who could face investigation for crimes against humanity carried out by security forces in their crackdown against the anti-government uprising.

The U.N. experts indicated that the list goes as high as President Bashar Assad.

Experts say the list is initially likely to be more of a deterrent against further abuses than a direct threat to the Assad regime. Syria isn’t a member of the International Criminal Court, so the court’s jurisdiction doesn’t apply there, and Russia would likely block any moves in the U.N. Security Council to refer the country to the tribunal, which is based in The Hague.

Thousands of Syrians have died in the violence since March, and the panel, citing what it called a reliable source, said at least 500 children are among the dead.

British Foreign Secretary William Hague said nations were considering action against Syria in meetings on the sidelines of an international conference in London. Mr. Hague said he would discuss “what we can achieve” with U.S. Secretary of State Hillary Rodham Clinton and many of the Arab League leaders .

Officials say Britain, the United States, Turkey, Qatar and others plan talks on the margins of a conference on Somalia.

At a major meeting in Tunis set for Friday, more than 70 nations are expected to look at ways to assist Mr. Assad’s opponents, who now include defected military officers and soldiers.

Mr. Hague told BBC radio that military intervention was very unlikely, as “the consequences of any outside intervention are much harder to foresee.”

A senior EU official said foreign ministers meeting in Brussels next week will add seven Syrian government ministers to those already sanctioned. Sanctions include asset freezes and visa bans for officials, commanders of the security forces and others considered responsible for human rights abuses.

The official, who spoke on condition of anonymity because of EU rules, said additional restrictions may be imposed on Syria‘s central bank, on imports of precious metals from the country, and on cargo flights.

The EU already has sanctioned more than 70 Syrians and 19 organizations and has banned imports of Syrian crude oil.
