尼日利亚选举集会发生人群踩踏事故，11人死亡。

The rally in the southern city of Port Harcourt was part of President Goodluck Jonathan's election campaign ahead of a poll due in April.

At least 29 others are said to have been injured at the rally, which was held in a crowded sports stadium.

President Jonathan has ordered an investigation¹ and said the incident was "sad, unfortunate and regrettable," adding: "I mourn with those who mourn."

The crowd panicked after a policeman fired in the air to try to disperse²（分散，传播） crowds at the gates as people left the rally, according to witnesses.

"There was a huge crowd, the place was completely full," Ken³ Saro-Wiwa, President Jonathan's special assistant on international affairs, told Reuters news agency.

"It is a sad end to what had been a great day," said Mr Saro-Wiwa.

President Jonathan, whose People's Democratic Party have won every presidential vote since the return to civilian⁴ rule in 1999, is favourite to win April's election.
