Wiesbaden, Germany - German federal police appealed to the public Thursday to help track down two missing Islamists, one of them a German convert, who were suspected of membership in a terrorist group.

Eric Breininger, a 21-year-old German, and Houssain al-Malla, a 23- year-old Lebanese, were last seen in the zone along the Pakistan- Afghan border. Police suspected they might have come back quietly into Germany.

The Federal Crime Office BKA showed photos of the two men on its web page listing the most wanted suspects in the country.

Police said Breininger, who from Saarland state in the west of the country, had recorded an internet video in which he spoke of carrying out a suicide attack and supported jihad or holy war.

But a spokesman said there was no concrete evidence Breininger was plotting an actual attack.

The BKA said Breininger and al-Malla were associates of three men, two of them German converts, who were arrested last year after stockpiling bomb-making chemicals. Breininger had shared an apartment with one of the detained suspects, then fled abroad.

Their group was affiliated to the Islamic Jihad Union (IJU), often described as a successor to al-Qaeda. (dpa)
