"The Indonesian president will attend the OIC emergency meeting and Indonesia has strong position to influence and reject the US decision recognizing Jerusalem as Israeli capital," spokesman for Hamas political bureau, Dr Maher Salah here on Thursday.
He made the remarks on the sidelines of a United Malay National Organization (UMNO) meeting.
President Joko Widodo (Jokowi) is set to attend the OIC meeting which will discuss US President Donald Trump`s recognition of Jerusalem as Israeli capital on Dec 13.
Maher said the Indonesian government can also encourage a strong expression of public anger to oppose the decision and do several things that Hamas will deliver.
"The Indonesian government is Palestine`s fellow. We praise Indonesia for its roles played at international or international organization level," he said.
He said his side needs much support for Palestine at all levels including political and economic levels.
"We expect Arab countries and Muslim countries to support us," he said.
