MEDAN, Indonesia (AFP) - An Indonesian provincial speaker died after he was beaten by a mob Tuesday which stormed the local parliament building carrying a coffin, officials and witnesses said. The protesters blamed North Sumatra provincial speaker Azis Angkat for delays in the creation of a new province as approved recently by five local districts."If it isn't signed we'll put Azis in this coffin," one of protesters shouted before the mob broke into the provincial parliament, where the speaker was meeting with other lawmakers. They smashed the entrance and windows of the building and rushed to the first-floor meeting room carrying the wooden coffin, an AFP correspondent witnessed. Angkat, from the Golkar party, tried to flee but he was caught and severely beaten before police could intervene. He died later in hospital of a heart attack, according to doctors.
