Brown invited to Gaza discussions
Gordon Brown was among global leaders invited to the talks
Gordon Brown has been invited to join world leaders in Egypt for a summit on the crisis in Gaza.
The discussions in Sharm el Sheikh later will be chaired by Egyptian President Hosni Mubarak and French President Nicolas Sarkozy.
The UK prime minister was among those asked to attend the talks but Downing Street said it could not confirm whether he would be there.
The summit comes after Israel declared a unilateral ceasefire in Gaza.
A Downing Street spokesman said: "That invitation is under consideration. No 10 is unable to confirm that he will attend."
German Chancellor Angela Merkel is believed to have agreed to take part, along with the United Nations Secretary-General, Ban Ki-Moon and the Palestinian President, Mahmoud Abbas.
Mr Brown has already offered UK naval resources to help monitor the conflict and help ensure protection and monitoring of the crossings into Gaza.
Foreign Secretary David Miliband, meanwhile, has welcomed Israeli Prime Minister Ehud Olmert's announcement of the ceasefire as a "huge relief".
Mr Miliband said the country had listened to international pressure and it was now "imperative" for Hamas to stop its rocket attacks on Israel.
He also called for the Gaza strip to be opened up to aid workers as quickly as possible.
Mr Olmert said Israel's operation in Gaza had fully achieved its aims, with Hamas badly damaged militarily and in terms of infrastructure.
Earlier, a Hamas spokesman said it would fight until its demands were met, including an Israeli withdrawal.
