Talks aimed at securing a ceasefire in Gaza are stalling over the extent of Israeli forces' withdrawal from the Palestinian enclave, Palestinian and Israeli sources familiar with the negotiations in Doha said on Saturday.

Senior Palestinian officials accuse Israel of deliberately stalling the negotiations in Qatar during the prime minister's US visit.

Indirect talks between Hamas and Israel for a ceasefire in Gaza are being held up by Israel's proposals to keep troops in the territory, two Palestinian sources with knowledge of the discussions told AFP on Saturday.

Being detained for more than 100 days without charge with the threat of deportation looming over him did not break the spirit of Palestinian student activist Mahmoud Khalil, he told CNN, but he can never forgive being prevented from being present at the birth of his son.

His complaint alleges he was falsely imprisoned, maliciously prosecuted and smeared as an anti-Semite. He said he either wants $20 million or an apology from the administration.
