5.40pm: This is the last update of the day. Thanks for all your comments.

In an interactive, the Guardian has gathered more testimonies given by some of those on the march of Coptic Christians in Cairo on Sunday night that ended with 26 dead and more than 500 injured. Many of them have been translated into English for the first time and directly contradictthe claims made by the Supreme Council of the Armed Forces in Wednesday's press conference regarding the origins and nature of the violence

Here are some quotes from the testimonies:

Bishoy Saad

The soldier at the tank hatch was opening machine gun fire in every direction … we could just hear screams and the window glass in the building next to Maspero shattering from the gunfire

Ragy El-Kashef

I saw three soldiers carrying a corpse and throwing it into the Nile … I saw scenes with my own eyes that will haunt me forever

Khaled El-Sherbini

The Copts (men, women, children and elders) were being beaten by thugs … no not 
beaten, annihilated

Hani Bushra

The order to use live ammunition was made in front of me … This is not religious strife, this is state sponsored terrorism.

Lobna Darwish

I found a woman screaming … I ran to hug her, and her husband was shot dead by her feet.

5.27pm: Terrorist groups have expressed interest in obtaining some of the thousands of shoulder-launched missiles that have gone missing in Libya and the issue has become a priority for the Obama administration, a senior US official said. From AP:

Andrew Shapiro, assistant secretary of state for political-military affairs, said on Friday the missiles "could pose a threat to civil aviation."

"We know that terrorist groups have expressed interest in obtaining these weapons," he said, adding that the issue issue of securing the weapons was a priority for President Barack Obama and Secretary of State Hillary Clinton.

Libya was believed to have about 20,000 such missiles in its arsenals before civil war began in March, Shapiro said. Although many were destroyed by NATO air strikes, thousands are missing.

"The possibility that these weapons may cross borders is an area of considerable concern," Shapiro said. "That's why [the] US has been working with countries bordering Libya to prevent (proliferation)."

5.10pm: There has been a huge demonstration in Yemen's capital Sana'a, calling on President Ali Abdullah Saleh to stand down, al-Arabiya reports. But there was also a counter-protest in support of Saleh.

The demonstrators, who protest organisers said numbered in the hundreds of thousands, called for the veteran leader to go on trial.

"There will be no immunity... Saleh and his cronies must face trial," chanted the protesters, gathered after weekly Muslim prayers as on every Friday since the outbreak of their campaign in late January.

Troops of dissident General Ali Mohsen al-Ahmar, who switched sides in March, were out in force to protect the demonstrators.

At a rival protest, tens of thousands of pro-regime demonstrators gathered near the presidential palace in southern Sana'a swearing to stand by Saleh who has been in power for the past three decades.

"The people want Ali Abdullah Saleh... With our souls, with our blood, we will sacrifice ourselves for you, Saleh," they chanted, in images broadcast by state television.

The report also says that the Gulf Co-operation Council has rejected proposed amendments to its Yemen initiative that would see Saleh remain in power until early presidential polls are held.

4.46pm: Médecins Sans Frontières says 10,000 residents are trapped by the fighting in Sirte and conditions in the main hospital are dire and unsafe.

Speaking from Ibn Sina hospital on Thursday, Dr Gabriele Rossi, MSF emergency co-ordinator, said:

The estimated 10,000 people who are still here are in the north part of town and are completely trapped by the fighting. There is no water or electricity.

In the hospital we have electricity, thanks to a generator, but until today there was no water. The atmosphere in the hospital is extremely heavy. There are about 50 patients, all with trauma wounds, fractures or burns, and all in need of surgery. Most of the patients are young adults, but we also have some women and children who have been injured in the fighting.

Without water it's impossible to do any kind of surgical intervention. The wounds of some patients are really bad and very infected. They need urgent surgical debridement. The situation is very serious.

Ibn Sina hospital is in a very damaged state, with signs of the heavy fighting. All the patients are on the ground floor, while the first floor and the basement are taken up with about 50 people who are sheltering from the violence and waiting for the chance to leave.

Security-wise, the hospital is not safe. Yesterday and today, there have been a lot of fighters entering the hospital with guns, checking every patient and looking for we don't know who. It is very important that hospitals, medical staff and ambulances are allowed to provide aid unhindered and in safety.

MSF says six people died on Thursday night, after this interview, because they could not be operated on.
