Emergency teams in eastern Turkey are working by floodlight to find more survivors of Sunday's earthquake as temperatures

plummet

to below zero. At least 260 people were killed in the quake; more than 1,000 were injured, and hundreds of others are missing. A BBC correspondent in the town of Ercis says there are about 80 sites where apartment blocks collapsed, each block being home to about 100 people. Earlier, five people were pulled alive from the rubble.

Egypt and Israel have reached an agreement under which 25 Egyptian prisoners held in Israel will be released in exchange for an Israeli American held in Egypt. Egyptian television named the man as Ilan Grapel, who was suspected of spying for Israel and had been detained since June. The deal is yet to be approved by the Israeli cabinet. The agreement follows the Egyptian-brokered

swap

between Israel and Hamas in which an Israeli soldier, Gilad Shalit, was freed in exchange for more than 1,000 Palestinian prisoners.
