Israel could annex more of West Bank: minister

"If the Palestinians take such a unilateral line, Israel should also consider ... passing a law to annex some of the settlements," Environment Minister Gilad Erdan, a close ally of Prime Minister Benjamin Netanyahu, told Israel Radio.

Without setting a timeframe, Palestinian officials said on Sunday the Palestinians planned to go to the U.N. Security Council in an effort to secure international support for an independent state in the West Bank and Gaza Strip.

Palestinians attributed the move to frustration at the lack of progress in peace talks, which have been stalled for a year. Palestinian President Mahmoud Abbas has said negotiations cannot resume until Israel halts settlement expansion.

The Palestinian remarks on possible unilateral steps prompted a warning from Netanyahu, who said in a speech on Sunday that only peace talks with Israel would secure a Palestinian state.

"There is no substitute for negotiations between Israel and the Palestinian Authority and any unilateral path will only unravel the framework of agreements between us and will only bring unilateral steps from Israel's side," Netanyahu said.
