Iraqi MPs have again delayed a session needed to elect a new leadership in the face of a jihadist-led Sunni rebellion in the north and west.

Iraq's politicians have been urged to unite but paralysis has continued.

The session, scheduled for Tuesday, has been postponed for a month.

Meanwhile a senior general, Maj Gen Najm Abdullah al-Sudani, was "martyred on the field of battle" in fighting to the west of Baghdad, said a statement from Prime Minister Nouri Maliki.

Parliament's first meeting last week had been due to elect a speaker, but ended after less than two hours when Kurdish and Sunni Arab MPs walked out, depriving it of a quorum.

As the leader of the bloc that won the most votes in April, Mr Maliki has demanded the right to attempt to form a governing coalition.

But he has faced calls from his Sunni, Kurdish and Shia opponents to step down because of his handling of the current security crisis, as well as what they say are the sectarian and authoritarian policies he has pursued during his previous two terms in office.

Iraq's most senior Shia cleric, Ayatollah Ali al-Sistani, had called on all parties to agree on the appointments before parliament convened.
