Bomb explosion
 
On Tuesday, Palestinian fighters exploded a bomb outside a major security compound occupied by Hamas forces in Gaza, officials said.
 
No one was injured in the blast, security sources said. Officials said that the bomb was thrown into a garbage container from a vehicle that drove by the compound, which was once a headquarters of Fatah.
 
Also on Tuesday, Mahmoud Abbas, the Palestinian president, arrived in the Egyptian city of Alexandria, where he is to meet Hosni Mubarak, his Egyptian counterpart.
 
The meeting comes within framework of ongoing co-ordination and consultation between the two sides.
 
The two sides will also discuss the situation in the Palestinian territories, resumption of peace process as well as the international conference for peace called for by George Bush, the US president.
