2010 GMT: Al Jazeera English summarises the pro-democracy demonstrations today in Bahrain:
Thousands of protesters have gathered outside the prime minister's office in Bahrain to demand that he step down, as their campaign for reform in the tiny Gulf nation enters its fourth week.
The demonstrators massed on Sunday at the Al-Qudaibiya Palace [Ministers' Council complex] in the capital, Manama, chanting slogans against the government and King Hamad, but failed to disrupt a government meeting in progress there.
Demonstrators shouted "Topple Hamad! Topple Hamad!" and "Hey Khalifa, get out! Get out!", referring to the country's long-time prime minister, Sheikh Khalifa bin Salman al-Khalifa.
Al-Khalifa, who was presiding over a weekly meeting of government ministers inside the palace, later told the state-run Bahrain News Agency that changes are under way and the kingdom's "reform march will continue".
"The government's development policies will continue upbeat as we are determined more than ever to achieve our goal of upgrading the citizens' standards of living by providing them with the means of decent life," he said.
The demonstrators want al-Khalifa to step down over alleged corruption and a deadly crackdown on the opposition in which seven people were killed.
"We want the prime minister to go," Alaa al-Nasr, a 24-year-old demonstrator, was reported by the AFP news agency as saying.
Protesters on Sunday also chanted for the 2002 constitution, which they say gave too much power to the monarchy, to be scrapped.

According to The Sunday Times, the appearance of the eight-man SAS unit and diplomat angered the Libyan opposition, who ordered their detention in a military base.
A British Foreign Office spokeswoman and the Minister of Defence told AFP, "We can neither confirm nor deny the report."

The correspondent has been told by a regime official that Qaddafi forces have even moved into Benghazi, Libya's second city, and killed the head of the opposition council established there.
There is no evidence for any of the regime claims.

Later this morning, Qaddafi supporters came out on the streets. In what appears to be a cover story for developments, State TV is claiming that this was a celebration of regime triumphs in three cities other parts of Libya.
Witnesses quickly take the claims apart, reporting that in two of those cities, Tobruk and Misurata, there is no sign of a regime pushback. An opposition figure in Misurata says the only conflict is a standoff at a military academy with the remnants of Qaddafi forces; most of them, he says, have defected to the opposition.
AFP also reports that the oil port of Ras Lanuf in north-central Libya, taken by the opposition on Friday, is still in their control.
Elsewhere, the death toll at Friday's explosion at an ammunition depot, near opposition-held Benghazi in eastern Libya, has risen to 39.
0625 GMT: Catching up after a break on Saturday....
The military situation in Libya continues to hold attention, with conflicting and unclear news this morning. There is heavy gunfire in Tripoli this morning, but State TV claims this is from supporters of Libyan leader Muammar Qaddafi celebrating in the capital's Green Square. They are supposedly cheering the re-taking of Zawiyah, 55 km (35 miles) west of Tripoli --- where a front-line battle has taken place over two days --- Misurata, 210 km (130 miles) east of Tripoli, and even Tobruk in the far east of Libya.
However, rebel groups say that they are still in control of these areas. While there were reports yesterday that regime tanks were close to the main square of Zawiyah, shelling surrounding building, there was no indication of fighting in the other two cities. On Friday, footage from Misurata showed many thousands of people celebrating its liberation from the regime.
For most of the day, however, even Libya was overshadowed by a developing story in Egypt. After protesters occupied the State Security Headquarters in Alexandria on Friday, demonstrators --- again claiming that they wanted to prevent the destruction of documents --- gathered at headquarters in the 6 October and Nasr City sections of Cairo.
By the evening, after the immediate threat of more clashes was abated by the appearance of the Army, news was circulating of dramatic finds in the documents that had been saved from the shredder. The picture was being drawn of a state security system seeking the most intimate details --- one of the headline claims was that sex videotapes of prominent figures were held by the authorities --- on its citizens and foreigners in Egypt.
