BERLIN/DRESDEN, Germany (Reuters) - A Syrian refugee arrested in Germany on Monday was ready to strike imminently with attacks similar to those in Brussels and Paris, and was probably inspired by Islamic State, German officials said.
Jaber Albakr, 22, arrived in Germany in February last year during a migrant influx into the country and was granted temporary asylum in June 2015. He had not previously aroused suspicion, officials said.
Police had been looking for him since he evaded them during a raid on Saturday on an apartment in the eastern German city of Chemnitz, where they found 1.5 kg of highly-charged explosives.
They arrested him after acting on a tip-off that other Syrians were holding him at an apartment in Leipzig, around 60 kilometers (37 miles) northwest of Chemnitz.
"According to what we know, the preparations in Chemnitz are similar to the preparations for the attacks in Paris and Brussels," federal Interior Minister Thomas de Maiziere said in a statement.
Islamic State gunmen and bombers killed some 130 people in the French capital in November and the militant group claimed responsibility for suicide bomb attacks in the Belgian capital four months later that left at least 30 people dead.
Joerg Michaelis, president of the Saxony state criminal investigation office, told a news conference in Dresden that Albakr was likely to have been inspired by Islamic State: "The behavior of the suspect speaks for an IS context," he said.
That will prove unwelcome news for Chancellor Angela Merkel, whose conservatives have lost support to the far-right Alternative for Germany (AfD) party over her open-door policy toward refugees and migrants.
Stephan Mayer, a senior lawmaker with Merkel's Bavarian allies, the Christian Social Union (CSU), said Germany's security agencies needed to be consulted more intensively in the authorities' handling of refugees.
"Germany is in the crosshairs of Islamist terror, just like France, Belgium or Britain," Mayer told television station n-tv. "We must be very careful."
Merkel, who thanked the security services for their work, said last month she wished she could "turn back the time by many, many years" to have better prepared for last year's influx of almost 1 million migrants.
She has yet to say whether she will seek a fourth term as chancellor in a federal election next year.
Michaelis said the explosives found in the Chemnitz apartment were similar to those used in the Paris and Brussels attacks.
Markus Ulbig, interior minister in the eastern state of Saxony, told the Dresden news conference that investigations had not yet determined the target Albakr aimed to attack.
He added: "... the work (of the investigators) has shown that we have prevented an imminent attack."
Police identified a second suspect as 33-year-old Khalil A., who was also from Syria and entered Germany in November last year. He was arrested at Chemnitz station on Saturday and had been remanded in custody.
A spokesman for the federal interior ministry said it was too soon to say whether Albakr was part of a larger network. Two other suspects detained on Saturday were released on Sunday.
In July, the Islamic State militant group claimed responsibility for two attacks in the western German state of Bavaria -- one a train near Wuerzburg and the other at a music festival in Ansbach that wounded 20 people.
